P(t < tc) = P(t < tc) = 0.05

using t table at df = 19

tc = ±1.729

So value is tc = (-1.729, 1.729)

P-value:

P(t > ItstatI) = p-value

P(t > I1.57I) = p-value

Using t-table

p-value = 0.1329

given

α = 0.10

So, p-value < α

Do not reject Null hypothesis.

Peter gets a salary of $125 per week. He wants to buy a new television that cost $3,960. If he saves $55 per week, which of the following expressions could he use to figure out how many weeks it will take him to save up enough money to buy the new TV ?

The solutions to the equation cos(x) = 0.27 on the interval 0 ≤ x < 2π are a ≈ 1.279 and b ≈ 5.006, where a < b. These solutions can be obtained by taking the inverse cosine of 0.27 and reflecting it across the x-axis.

To solve the equation cos(x) = 0.27 on the interval 0 ≤ x < 2π, we need to find the values of x that satisfy this equation. Since cosine is a periodic function with a period of 2π, there may be multiple solutions within the given interval.

First, let's find the principal solution by taking the inverse cosine (arccos) of both sides of the equation:

x = arccos(0.27)

Using a calculator, we find that arccos(0.27) ≈ 1.279.

Now, we have one solution x = 1.279 within the interval 0 ≤ x < 2π. However, we need to find the other solution as well.

Since cosine has a symmetrical property around the x-axis, we can find the second solution by reflecting the principal solution across the x-axis. To do this, we subtract the principal solution from 2π:

x2 = 2π - x1

x2 = 2π - 1.279

Calculating this, we get x2 ≈ 5.006.

Therefore, we have two solutions to the equation cos(x) = 0.27 on the interval 0 ≤ x < 2π: a ≈ 1.279 and b ≈ 5.006, where a < b.

Let's verify these solutions:

For x = 1.279:

cos(1.279) ≈ 0.27

The cosine of 1.279 is approximately 0.27, satisfying the equation.

For x = 5.006:

cos(5.006) ≈ 0.27

The cosine of 5.006 is also approximately 0.27, confirming the validity of this solution.

Both solutions a ≈ 1.279 and b ≈ 5.006 fulfill the equation cos(x) = 0.27 on the interval 0 ≤ x < 2π.

It's worth noting that cosine has a periodic nature, repeating every 2π. Therefore, if we continue to add or subtract multiples of 2π to the solutions a and b, we will obtain infinitely many solutions that satisfy the equation cos(x) = 0.27 within the interval 0 ≤ x < 2π.

In summary, the solutions to the equation cos(x) = 0.27 on the interval 0 ≤ x < 2π are a ≈ 1.279 and b ≈ 5.006, where a < b. These solutions can be obtained by taking the inverse cosine of 0.27 and reflecting it across the x-axis.

The authors of "The Randomness of the National Lottery" completed in 2002 hit a snag when they found that one numbered ball, 38, was drawn so often that they believed there was bias in the selections.

Haigh and Goldie found that over 637 draws, each number should be drawn between 70 and 86 times. But they found that 38 came up 107 times, 14 times more than the next most drawn ball. The chance that a particular number was drawn more than 107 times in 637 draws was less than 1%.

Therefore, the authors were correct that the chance is under 1%.A spokesperson defending the lotteries randomness criticized the author's conclusion by saying that if you travel through an awful lot of data, you are always going to uncover patterns somewhere in her statement. Her statement is consistent with the decision-making processes of the hypothesis testing.

Therefore, it is entirely reasonable to suggest that the authors' approach was correct. There are always going to be anomalies in a lottery drawing that may or may not be a result of some kind of fraud.

The interval of convergence, I, is (7 - R, 7 + R), which in this case is (7 - 1, 7 + 1) = (6, 8).

To find the radius of convergence, R, of the series, we can use the ratio test. The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is L as n approaches infinity, then the series converges if L < 1 and diverges if L > 1.

In this case, the series is given by:

∑ (n = 0 to ∞) [(x - 7)^n * (n^3 + 1)]

Let's apply the ratio test to find the radius of convergence, R:

lim (n → ∞) |[(x - 7)^(n+1) * ((n+1)^3 + 1)] / [(x - 7)^n * (n^3 + 1)]|

Simplifying the expression:

lim (n → ∞) |(x - 7) * ((n+1)^3 + 1) / (n^3 + 1)|

As n approaches infinity, the 1 terms become negligible compared to the other terms:

lim (n → ∞) |(x - 7) * (n^3 + 3n^2 + 3n + 1) / n^3|

Using the fact that lim (n → ∞) (1 + 1/n) = 1, we can simplify further:

lim (n → ∞) |(x - 7) * (1 + 3/n + 3/n^2 + 1/n^3)|

Taking the absolute value:

| x - 7 | * 1

Since the limit does not depend on n, we can take the absolute value of x - 7 outside of the limit:

| x - 7 | * lim (n → ∞) (1 + 3/n + 3/n^2 + 1/n^3)

The limit evaluates to 1:

| x - 7 |

For the series to converge, | x - 7 | < 1. Therefore, the radius of convergence, R, is 1.

To find the interval of convergence, I, we need to determine the values of x for which the series converges. Since the center of the series is 7, the interval of convergence will be centered around x = 7 and will extend R units to the left and right.

Therefore, the interval of convergence, I, is (7 - R, 7 + R), which in this case is (7 - 1, 7 + 1) = (6, 8).

The volume is 4π (absolute value) units cubed. To find the volume generated by rotating the region bounded by the curves y = 3x^2 and y = 18x - 6x^2 about the y-axis, we can use the method of cylindrical shells.

The first step is to determine the limits of integration. We need to find the x-values at which the curves intersect. Set the equations for the curves equal to each other:

3x^2 = 18x - 6x^2

Rearrange the equation and set it equal to zero:

9x^2 - 18x = 0

Factor out 9x:

9x(x - 2) = 0

This gives us two possible solutions: x = 0 and x = 2. These are the limits of integration.

Now, we need to determine the height and radius of each cylindrical shell. The height of each shell is the difference between the y-values of the curves at a particular x-value. The radius of each shell is the x-value itself.

Let's denote the height as h and the radius as r. The volume of each cylindrical shell is given by:

dV = 2πrh dx

Integrating this expression from x = 0 to x = 2 will give us the total volume:

V = ∫[0,2] 2πrh dx

To calculate the height (h), we subtract the equation of the lower curve from the equation of the upper curve:

h = (18x - 6x^2) - (3x^2) = 18x - 9x^2

The radius (r) is simply the x-value:

r = x

Now, we can substitute these values into the integral expression:

V = ∫[0,2] 2π(18x - 9x^2)(x) dx

Simplifying:

V = 2π ∫[0,2] (18x^2 - 9x^3) dx

To find the antiderivative, integrate each term separately:

V = 2π [6x^3/3 - 9x^4/4] |[0,2]

V = 2π [(2^3/3)(6) - (2^4/4)(9) - (0)]

V = 2π [16 - 18]

V = 2π [-2]

V = -4π

The volume generated by rotating the region about the y-axis is -4π (negative value indicates that the region is oriented below the y-axis).

The mean squared error (MSE) of the given forecasts is 7500. The MSE provides an indication of the average squared deviation between the actual sales and the forecasted sales.

The mean squared error (MSE) is a measure of the average squared difference between the actual values and the forecasted values. It provides a quantification of the accuracy of a forecasting model.

To calculate the MSE, we need to find the squared difference between the actual sales and the forecasted sales for each month, sum up these squared differences, and then divide by the number of observations.

Let's calculate the MSE for the given forecasts:

Month Actual Sales Forecasted Sales Squared Difference (Actual - Forecast)^2

Jan. 614 600 196

Feb. 480 480 0

Mar. 500 450 2500

Apr. 500 600 10000

To calculate the MSE, we sum up the squared differences and divide by the number of observations (in this case, 4):

MSE = (196 + 0 + 2500 + 10000) / 4

MSE = 1250 + 1250 + 2500 + 2500

MSE = 7500

Therefore, the mean squared error (MSE) of the given forecasts is 7500.

The MSE provides an indication of the average squared deviation between the actual sales and the forecasted sales. A lower MSE value indicates a better fit between the actual and forecasted values, while a higher MSE value suggests a larger deviation and lower accuracy of the forecasts.

In this case, the MSE of 7500 suggests that the forecasted sales deviate, on average, by approximately 7500 units squared from the actual sales. It's important to note that without context or comparison to other forecasting models or benchmarks, it is difficult to determine whether this MSE value is considered good or bad. The interpretation of the MSE value should be done in relation to other similar forecasts or industry standards.

The probability that a sample size of 100 has a sample proportion of 0.65 or less, given a population proportion of 0.7, is approximately 0.1379 or 13.79%.

To calculate the probability, we can use the normal distribution approximation for the sampling distribution of sample proportions.

The mean of the sampling distribution of sample proportions is equal to the population proportion, which is 0.7 in this case.

The standard deviation of the sampling distribution is given by the formula:

σ = sqrt((p * (1 - p)) / n)

where p is the population proportion (0.7) and n is the sample size (100).

σ = sqrt((0.7 * (1 - 0.7)) / 100) = sqrt(0.21 / 100) ≈ 0.0458

To find the probability that the sample proportion is 0.65 or less, we need to standardize the value using the formula:

z = (x - μ) / σ

where x is the sample proportion (0.65), μ is the mean of the sampling distribution (0.7), and σ is the standard deviation of the sampling distribution (0.0458).

Plugging in the values, we get:

z = (0.65 - 0.7) / 0.0458 ≈ -1.09

Now, we need to find the area under the standard normal distribution curve to the left of z = -1.09. This can be done using a standard normal distribution table or a statistical calculator.

Using a standard normal distribution table or a calculator, the probability associated with z = -1.09 is approximately 0.1379.

Therefore, the probability that a sample size of 100 has a sample proportion of 0.65 or less, given a population proportion of 0.7, is approximately 0.1379 or 13.79%.

When the diameter is 100 mm, the volume is increasing at a rate of 300π mm^3/s.

We use the derivative of the volume equation with respect to time. Given that the radius is increasing at a rate of 3 mm/s, we can differentiate the volume equation and substitute the values.

The equation for the volume (V) of a sphere with radius (r) in mm is given by: V = (4/3)πr^3 mm^3

To find the radius of a sphere when its diameter is 100 mm, we can divide the diameter by 2: Radius = Diameter / 2 = 100 mm / 2 = 50 mm

When the radius is 50 mm, we can substitute this value into the volume equation to find the volume: V = (4/3)π(50^3) mm^3 = (4/3)π(125000) mm^3

To determine how fast the volume is increasing when the diameter is 100 mm, we need to find the derivative of the volume equation with respect to time. Since the radius is increasing at a rate of 3 mm/s, we can express the derivative of the volume with respect to time as dV/dt.

dV/dt = (dV/dr) * (dr/dt)

We know that dr/dt = 3 mm/s and we can differentiate the volume equation to find dV/dr:

(dV/dr) = 4πr^2 mm^3/mm

Substituting the values:

dV/dt = (4πr^2) * (dr/dt) = (4π(50^2)) * (3) mm^3/s

Simplifying:

dV/dt = 300π mm^3/s

Therefore, when the diameter is 100 mm, the volume is increasing at a rate of 300π mm^3/s.

The radius of convergence, r is 1 and interval of convergence, i, of the series. [infinity] (x − 14)n n2 1 n = 0 is [13, 15), including 13 but excluding 15.

To find the radius of convergence, we can use the ratio test:

lim |(x - 14)(n+1)^2 / n^2| = lim |(x - 14)(n+1)^2| / n^2

= lim (x - 14)(n+1)^2 / n^2

Since the limit of the ratio as n approaches infinity exists, we can apply L'Hopital's rule:

lim (x - 14)(n+1)^2 / n^2 = lim (x - 14)2(n+1) / 2n

= lim (x - 14)(n+1) / n

= |x - 14|

So the series converges if |x - 14| < 1, and diverges if |x - 14| > 1. Therefore, the radius of convergence is 1.

To find the interval of convergence, we need to check the endpoints x = 13 and x = 15.

When x = 13, the series becomes:

∑ [13 - 14]^n n^2 = ∑ (-1)^n n^2

This is an alternating series that satisfies the conditions of the alternating series test, so it converges.

When x = 15, the series becomes:

∑ [15 - 14]^n n^2 = ∑ n^2

This series diverges by the p-test.

Therefore, the interval of convergence is [13, 15), including 13 but excluding 15.

Since P1 and P2 are partitions of [a, b], the union of the subintervals in P1 and P2 gives us a common refinement partition P = P1 ∪ P2. Therefore, P is a refinement of both P1 and P2

To understand why U(f) ≥ L(f, P), we need to define the upper sum U(f) and the lower sum L(f, P) in the context of partitions.

For a function f defined on a closed interval [a, b], let P = {x0, x1, ..., xn} be a partition of [a, b], where a = x0 < x1 < x2 < ... < xn = b. Each subinterval [xi-1, xi] in the partition P represents a subinterval of the interval [a, b].

The upper sum U(f) of f with respect to the partition P is defined as the sum of the products of the supremum of f over each subinterval [xi-1, xi] multiplied by the length of the subinterval:

U(f) = Σ[1, n] sup{f(x) | x ∈ [xi-1, xi]} * (xi - xi-1)

The lower sum L(f, P) of f with respect to the partition P is defined as the sum of the products of the infimum of f over each subinterval [xi-1, xi] multiplied by the length of the subinterval:

L(f, P) = Σ[1, n] inf{f(x) | x ∈ [xi-1, xi]} * (xi - xi-1)

Now, let's explain why U(f) ≥ L(f, P).

Consider any subinterval [xi-1, xi] in the partition P. The supremum of f over the subinterval represents the maximum value that f can take on within that subinterval, while the infimum represents the minimum value that f can take on within that subinterval.

Since the supremum is always greater than or equal to the infimum for any subinterval, we have:

sup{f(x) | x ∈ [xi-1, xi]} ≥ inf{f(x) | x ∈ [xi-1, xi]}

Multiplying both sides of this inequality by the length of the subinterval (xi - xi-1), we get:

sup{f(x) | x ∈ [xi-1, xi]} * (xi - xi-1) ≥ inf{f(x) | x ∈ [xi-1, xi]} * (xi - xi-1)

Summing up these inequalities for all subintervals [xi-1, xi] in the partition P, we obtain:

Σ[1, n] sup{f(x) | x ∈ [xi-1, xi]} * (xi - xi-1) ≥ Σ[1, n] inf{f(x) | x ∈ [xi-1, xi]} * (xi - xi-1)

This simplifies to:

U(f) ≥ L(f, P)

Therefore, U(f) is always greater than or equal to L(f, P).

Now, let's prove Lemma 7.2.6, which states that if P1 and P2 are two partitions of the interval [a, b], then L(f, P1) ≤ U(f, P2).

Proof of Lemma 7.2.6:

Let P1 = {x0, x1, ..., xn} and P2 = {y0, y1, ..., ym} be two partitions of [a, b].

We want to show that L(f, P1) ≤ U(f, P2).

Since P1 and P2 are partitions of [a, b], the union of the subintervals in P1 and P2 gives us a common refinement partition P = P1 ∪ P2.

Therefore, P is a refinement of both P1 and P2

Sorry for bad handwriting

a) The mean (μ) of the number of right-handers can be found using the formula μ = n * p, where n is the number of trials and p is the probability of success.

μ = 10 * 0.9 = 9 The standard deviation (σ) can be found using the formula σ = √(n * p * (1 - p)).

σ = √(10 * 0.9 * 0.1) ≈ 0.95

b) To find the probability that they're not all right-handed, we can use the complement rule. The complement of "not all right-handed" is "at least one left-handed". So, the probability is 1 minus the probability that all are right-handed.

P(not all right-handed) = 1 - P(all right-handed) = 1 - (0.9)^10 ≈ 0.651

c) To find the probability that there are no more than 9 righties, we can sum the probabilities of having 0, 1, 2, ..., 9 right-handers.

P(no more than 9 righties) = P(0) + P(1) + P(2) + ... + P(9)

= (0.1)^0 + (0.1)^1 + (0.1)^2 + ... + (0.1)^9 ≈ 0.999

d) To find the probability that there are exactly 5 of each, we can use the binomial coefficient formula. The probability of having exactly k successes in n trials is given by:

P(exactly k successes) = (n choose k) * p^k * (1 - p)^(n - k)

P(exactly 5 right-handers and 5 left-handers) = (10 choose 5) * (0.9)^5 * (0.1)^5 ≈ 0.02953

e) To find the probability that the majority is right-handed, we need to sum the probabilities of having 6, 7, 8, 9, or 10 right-handers.

P(majority is right-handed) = P(6) + P(7) + P(8) + P(9) + P(10)

= (0.9)^6 + (0.9)^7 + (0.9)^8 + (0.9)^9 + (0.9)^10 ≈ 0.912

In summary, the mean number of right-handers is 9, the standard deviation is approximately 0.95. The probability that they're not all right-handed is about 0.651. The probability that there are no more than 9 righties is approximately 0.999. The probability of having exactly 5 of each is around 0.02953. Lastly, the probability that the majority is right-handed is approximately 0.912.

To find the initial cost of the bedspread before the 15% discount, we can use the formula:

Initial cost = Final cost / (1 - Discount rate)

In this case, the final cost is $38.25, and the discount rate is 15% or 0.15.

Initial cost = $38.25 / (1 - 0.15)

Initial cost = $38.25 / 0.85

Initial cost ≈ $45

Therefore, the initial cost of the bedspread before the 15% discount is approximately $45.

(a) The equilibria of the model can be found by setting dp/dt = 0 and solving for p. From the given differential equation, we have cp(1-p) - ep = 0. Rearranging this equation, we get cp - cp^2 - ep = 0. Factoring out p, we have p(cp - cp - e) = 0. Simplifying further, we find that the equilibria are p = 0 and p = (c - e)/c.

(b) To ensure that the nonzero equilibrium p = (c - e)/c lies between 0 and 1, we need the fraction to be positive and less than 1. This implies that c - e > 0 and c > e.

(c) The conditions for the nonzero equilibrium to be locally stable depend on the sign of the derivative dp/dt at that equilibrium. Taking the derivative dp/dt and evaluating it at p = (c - e)/c, we find dp/dt = (c - e)(1 - (c - e)/c) - e = (c - e)(e/c). For the equilibrium to be locally stable, we require dp/dt < 0. Therefore, the condition for local stability is (c - e)(e/c) < 0, which can be simplified to e < c.

In conclusion, the equilibria of the Levins model are p = 0 and p = (c - e)/c. The nonzero equilibrium lies between 0 and 1 when c > e, and it is locally stable when e < c.

The two sides are not equal, the conclusion of Green's Theorem does not hold for the given vector field F = -2yi + 2xj and the disk domain R: x² + y² < a².

To verify the conclusion of Green's Theorem, we need to evaluate both sides of the equation for the given vector field F = -2yi + 2xj and the domains of integration, which are the disk R: x² + y² < a² and its bounding circle C: r = a(cost)i + a(sint)j, 0 ≤ t ≤ 2π.

Green's Theorem states:

∬(R) (∂Q/∂x - ∂P/∂y) dA = ∮(C) P dx + Q dy

where P and Q are the components of the vector field F.

First, let's evaluate the left-hand side (LHS) of the equation using double integration:

LHS = ∬(R) (∂Q/∂x - ∂P/∂y) dA

Since P = -2y and Q = 2x, we have:

∂Q/∂x = 2

∂P/∂y = -2

Substituting these values into the equation, we get:

LHS = ∬(R) (2 - (-2)) dA

= ∬(R) 4 dA

To evaluate this double integral, we can use polar coordinates since the domain of integration is a disk. In polar coordinates, we have:

x = rcosθ

y = rsinθ

The Jacobian determinant of the transformation is r, and the area element dA becomes r dr dθ.

The limits of integration for r are 0 to a, and for θ, it is 0 to 2π.

LHS = ∫(0 to 2π) ∫(0 to a) 4 r dr dθ

Integrating with respect to r first:

LHS = ∫(0 to 2π) [2r²] (from 0 to a) dθ

= ∫(0 to 2π) 2a² dθ

= 2a² ∫(0 to 2π) dθ

= 2a² * 2π

= 4πa²

Now, let's evaluate the right-hand side (RHS) of the equation by integrating along the bounding circle C:

RHS = ∮(C) P dx + Q dy

Parameterizing the circle C as r = a(cosθ)i + a(sinθ)j, we have:

dx = -a(sinθ)dθ

dy = a(cosθ)dθ

Substituting the values of P and Q, we get:

P dx = (-2y)(-a(sinθ)dθ) = 2a(sinθ)(-a(sinθ)dθ) = -2a²(sin²θ)dθ

Q dy = (2x)(a(cosθ)dθ) = 2a(cosθ)(a(cosθ)dθ) = 2a²(cos²θ)dθ

RHS = ∮(C) (-2a²(sin²θ)dθ) + (2a²(cos²θ)dθ)

Integrating with respect to θ from 0 to 2π:

RHS = ∫(0 to 2π) (-2a^2(sin²θ)dθ) + ∫(0 to 2π) (2a²(cos²θ)dθ

Both integrals evaluate to zero because sin²θ and cos²θ have a period of π, and integrating over a full period results in zero.

Therefore, RHS = 0.

Comparing the values of LHS and RHS, we have:

LHS = 4πa²

RHS = 0

The equation to determine slope of a line is given as follows:\[\text{slope}=\frac{\text{rise}}{\text{run}}\]

where, rise indicates the change in the y-value, and run indicates the change in the x-value, as we move from one point to the other.

Let us find the slope of the line passing through the points (6,2) and (-10,-3) using the above equation.

So, the slope is,\[\begin{aligned}\text{slope}&=\frac{\text{rise}}{\text{run}}\\&=\frac{\text{change in y-values}}{\text{change in x-values}}\\&=\frac{2-(-3)}{6-(-10)}\\&=\frac{2+3}{6+10}\\&=\frac{5}{16}\end{aligned}\]
