A researcher is evaluating the effectiveness of a new physical education program for elementary school children. The program is designed to reduce competition and increase individual self-esteem. A sample of n=36 children is selected and the children are placed in the new program. After 3 months, each child is given a standardized self-esteem test. The mean is M=43. For the general population of elementary school children, the scores on the self-esteem test are normally distributed with μ = 40 and σ = 8 . Conduct a two-tailed one-sample z-test at the α = .05 level.
a, State the null and alternative hypotheses in words and symbols.
b. Conduct the hypothesis test (use both the critical value and p-value approach). Show steps 3 and 4 of hypothesis testing.
If appropriate, compute and interpret Cohen’s d.
State the conclusion of your hypothesis test.

Answers

The mean self-esteem score after the program (M = 43) is not significantly different from the population mean self-esteem score (μ0 = 40) at the α = 0.05 level.

what is probability?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain.

a. The null hypothesis (H0) is that the new physical education program has no effect on the self-esteem scores of elementary school children, or in other words, the mean self-esteem score after the program (μ) is equal to the population mean self-esteem score (μ0): H0: μ = μ0 = 40.

The alternative hypothesis (Ha) is that the new program has an effect on the self-esteem scores, either positive or negative, or in other words, the mean self-esteem score after the program (μ) is not equal to the population mean self-esteem score (μ0): Ha: μ ≠ μ0.

b.

Step 1: Set up the hypothesis:

H0: μ = μ0 = 40

Ha: μ ≠ μ0

Step 2: Determine the significance level: α = 0.05

Step 3: Calculate the test statistic:

z = (M - μ0) / (σ / sqrt(n))

z = (43 - 40) / (8 / sqrt(36))

z = 1.5

Step 4: Determine the critical value or p-value:

For a two-tailed test with α = 0.05, the critical values are -1.96 and 1.96.

Since the calculated test statistic (z = 1.5) is not in the rejection region (it falls between -1.96 and 1.96), we fail to reject the null hypothesis.

Alternatively, we can calculate the p-value using a standard normal distribution table or a calculator. The p-value for a two-tailed test with z = 1.5 is 0.134. Since the p-value is greater than the significance level (p > α), we fail to reject the null hypothesis.

Cohen's d can be calculated as d = (M - μ0) / s, where s is the standard deviation of the population.

d = (43 - 40) / 8 = 0.375

This means that the mean self-esteem score of the sample is 0.375 standard deviations higher than the population mean self-esteem score.

Therefore,  The mean self-esteem score after the program (M = 43) is not significantly different from the population mean self-esteem score (μ0 = 40) at the α = 0.05 level.

Aaron has 2 pizzas left over from a sleepover.
He ate 1/8 of the leftover pizza
for lunch. How much of the pizza did he
eat? How much is left?

Answers

If Aron has 2 pizzas left from the sleepover, and he ate 1/8 of one pizza, that means he ate:

1/8 * 1 = 1/8 of a pizza

So he ate 1/8 of a pizza.

To find out how much pizza is left, we need to subtract the amount that he ate from the total amount of pizza. If he started with 2 pizzas and ate 1/8 of one pizza, that means there are:

2 - 1/8 = 15/8

So there are 15/8 (or 1 and 7/8) pizzas left

c.What is her cost per mile?

Answers

a. The total cost is $310.64. b. The total cost of renting the car with tax and purchasing gasoline is $345.99.

What distinguishes a fixed cost from a variable cost?

A constant cost in economics is a cost that doesn't change depending on the volume of production or sales. Rent, wages, and insurance premiums are some instances of fixed costs. Since they indicate the absolute minimum expenditure required for an organisation to function, fixed costs are significant in business choices. Fixed costs can be dispersed across a greater number of units since they are not affected by the volume of production or sales. This can lower the per-unit cost of manufacturing.

Given that, the car rents for $229.00 per week with no charge for mileage. Her gasoline cost is $81.64.

a. Total cost = $229.00 + $81.64 = $310.64

b. If the rental is subject to a 15% state and local tax, then the additional cost is:

0.15 x $229.00 = $34.35

$229.00 + $34.35 + $81.64 = $345.99

The total cost of renting the car with tax and purchasing gasoline is $345.99.

Two angles of a quadrilateral measure 140° and 60°. The other two angles are in a ratio of 7:9. What are the measures of those two angles?

Answers

In the quadrilateral the measure of angles in ratio 7 : 9 is 70° and 90°. respectively.

What is an angle?

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.

The sum of the angles of a quadrilateral is always 360 degrees.

So, we can start by finding the measure of the two unknown angles using the information that we have -

Let x be the measure of the smaller of the two unknown angles, then the measure of the larger angle is 9x and smaller angle is 7x (since the two angles are in a ratio of 7:9).

The sum of all four angles is 140° + 60° + 7x + 9x = 360°.

Simplifying this equation, we get -

140° + 60° + 16x = 360°

200° + 16x = 360°

16x = 160°

Dividing both sides by 16, we get -

x = 10°

So, the smaller of the two unknown angles is -

7x = 7 × 10° = 70°

The larger angle is -

9x = 9 × 10° = 90°

Therefore, the measures of the two unknown angles are 70° and 90°.

Write 10 sin(4t) - 9 cos(4t) in the form A sin (Bt + C). Roundto 3 decimal places, if necessary.

Answers

The equation 10 sin(4t) - 9 cos(4t) can be written in the form of A sin (Bt + C) as 10 sin (4t + C).

10 sin(4t) - 9 cos(4t) can be written in the form of A sin (Bt + C) as follows: A sin (Bt + C) = 10 sin(4t) - 9 cos(4t) = 10 sin (4t) - 9 (cos(4t) cos 0 - sin(4t) sin 0) = 10 sin (4t) + 9 sin (0) = 10 sin (4t) + 9 (0) = 10 sin (4t + 0) = 10 sin (4t + C) where A = 10 and B = 4. Thus, 10 sin (4t) - 9 cos (4t) can be written in the form of A sin (Bt + C) as 10 sin (4t + C).


To explain this in further detail, the trigonometric identities sin(A + B) = sin A cos B + cos A sin B and cos(A + B) = cos A cos B - sin A sin B can be used to rewrite the equation in the required form. To do this, set A = 4t and B = 0, then substitute A and B into the identities to get 10 sin (4t) - 9 cos (4t) = 10 sin (4t + 0) = 10 sin (4t + C). Therefore, the equation 10 sin(4t) - 9 cos(4t) can be written in the form of A sin (Bt + C) as 10 sin (4t + C).

Using the corresponding and alternate angles, we found the measures of the following angles:

1) m∠ABE = 82°

2) m∠EBF = 53°

3) m∠BFE = 45°

4) m∠BEF = 82°

What are corresponding angles?

Corresponding angles are those that are created when two parallel lines are intersected by another line, whether it be a transversal or a matching corner (i.e. the transversal). According to the definition of corresponding angles, when two parallel lines are intersected by a third line, the angles that are present at each intersection and are in the same relative position are said to be corresponding angles.

The angles created when a transversal cuts two straight lines are known as alternative angles, and they are formed on the opposite side of the transversal with regard to both lines.

Here the lines AC and DF are parallel to each other.

The line EB cuts them.

So corresponding angles are formed.

∠DEB = ∠ABG = 98°

Now ∠ABG + ∠ABE = 180°

So ∠ABE = 180 - ∠ABG = 180 - 98 = 82°

∠ABE + ∠EBF + 45° = 180°

82 + ∠EBF + 45 = 180

∠EBF = 53°

∠BFE = ∠FBE = alternate angles

∠BFE = 45°

∠BEF = ∠ABE = alternate angles

∠BEF = 82°

Therefore using the corresponding and alternate angles, we found the measures of the following angles:

1) m∠ABE = 82°

2) m∠EBF = 53°

3) m∠BFE = 45°

4) m∠BEF = 82°

The base 10 representatiοn οf the number 1406 (3 at the bοttοm) is 118.

Describe Base number?

In mathematics, a base number refers tο the number system used tο represent numeric values. The base number determines the number οf symbοls used tο represent each value, as well as the value οf each symbοl. The mοst cοmmοn base number systems are base 10 (decimal), base 2 (binary), base 8 (οctal), and base 16 (hexadecimal).

In base 10, we use 10 digits (0-9) tο represent all pοssible values. In binary, we use οnly twο digits (0 and 1) tο represent values. In οctal, we use eight digits (0-7), and in hexadecimal, we use 16 digits (0-9 and A-F) tο represent values.

Fοr example, the decimal number 125 can be represented in base 2 as 1111101, in base 8 as 175, and in base 16 as 7D.

Cοnverting a number frοm οne base tο anοther invοlves dividing the number by the base and repeatedly finding the remainder until the quοtient becοmes zerο. The remainders, read frοm bοttοm tο tοp, represent the digits οf the new number in the new base.

Tο cοnvert a number in base 3 tο base 10, we need tο multiply each digit οf the number by the cοrrespοnding pοwer οf 3, and then sum up the prοducts.

Starting frοm the rightmοst digit οf the number, the pοwers οf 3 increase by 1 fοr each digit tο the left. Sο, fοr the number 1406 (3 at the bοttοm), we have:

The radius r in millimeters of a platinum with L centimeters long with resistance 0.1 ohm is r equals 0.059L^1/2. How long is a wire with radius 0.236 millimeters?

rational exponents!

Answers

The length of the wire with a radius of 0.236 millimeters is 16.5 cm.

What is the length of the wire?

We are given the formula for the radius of a platinum wire in terms of its length L and resistance R:

[tex]r = 0.059L^{(1/2) } \ mm[/tex]

We are also told that the resistance of the wire is 0.1 ohm.

We can use the formula for the resistance of a wire in terms of its length L, cross-sectional area A, and resistivity rho:

R = ρL/A

where;

ρ is the resistivity of platinum, which is 10.6 x 10⁻⁸ ohm-meter.

We can rearrange this formula to solve for the cross-sectional area:

A = ρL/R

Substituting the given values, we have:

A = (10.6 x 10⁻⁸ ohm. m)(L m)/(0.1 ohm)

A = 1.06 x 10⁻⁶ m L

We can also use the formula for the area of a circle in terms of its radius:

A = πr²

Solving for the radius, we have:

r = √(A/π)

Substituting the expression for A, we have:

r = √[(1.06 x 10⁻⁶ m.L )/π]

Substituting the given radius of 0.236 mm, we can solve for the length L:

0.236 x 10⁻³ m = √[(1.06 x  10⁻⁶ m.L)/π]

Squaring both sides, we have:

(0.236 x 10⁻³ m)² = (1.06 x 10⁻⁶ m.L)/π

Solving for L, we have:

L = [(0.236 x 10⁻³ m)² π]/(1.06 x  10⁻⁶ m)

L = 0.165 m = 16.5 cm

The total area of the given composite figure found using the areas of right triangles and rectangle is 231.68sq. yards.

What is a composite figure?

Composite geometric figures are made from two or more geometric figures. Finding the area of a composite shape can be done using one of two broad approaches.

The total of the individual areas will represent the composite shape's area.

Determine the areas of the parts of the larger form that aren't part of the composite shape that are larger than the composite shape. The composite shape's area will be calculated as the difference between the larger shape's area and the areas of the larger shape's excluded portions.

The given composite figure consists of two right triangles and a rectangle.

The area of the figure is the sum of the areas of the right triangles and the rectangle.

Both the right triangle are the same.

So the area of one triangle = 0.5 * base * height = 0.5 * 6.4 * 12.8

                                                                = 40.96 sq. yards

So the total area of both triangles = 2 * 40.96 = 81.92 sq. yards.

Now the area of the rectangle = length * breadth = 14.9 * 12.8

                                                            = 190.72 sq. yards

The total area of the figure = 190.72+40.96 = 231.68 sq. yards.

Therefore the total area of the given composite figure found using the areas of right triangles and rectangle is 231.68sq. yards.

The sum of probabilities of all possible outcomes is 1, so we can write:

0.1 + 2x + x + 0.3 = 1

Simplifying this equation, we get:

3x + 0.4 = 1

3x = 0.6

x = 0.2

Therefore, the probability of landing on 3 is 0.2 and the probability of landing on 2 is 2x = 0.4.

If the spinner is spun 50 times, we can expect it to land on 2 approximately 0.4 * 50 = 20 times

Over the past 10 years, the population of an island has decreased by 2% The population of an island 10 years ago was 24000. What is the population of the island now?

Answers

Answer:

23,520

Step-by-step explanation:

The population of an island has decreased by 2% when the population was 24000. What we want to do is find out how much of a population is each percentage. We want to divide 24,000 with 100 because 24,000 is 100% of the population 10 years ago.

24,000 ÷ 100 = 240

Now we know 1% of the population is 240, but we want to find out 2% of the population. Now we want to multiply by 2.

240 × 2 = 480

Now we know the population has decreased by 480 over the last 10 years, but we want to know the population of the island now. This is easy, all we got to do is take the original population and subtract how much the population it has decreased over 10 years.

24,000 - 480 = 23,520

The population of the island now is 23,520

Hope this helps : )

Answer:

23,520

Step-by-step explanation:

What is a percentage?

A percentage is a ratio or a number expressed in the form of a fraction of 100. Percentages are often used to express a part of a total.

If the island had a population of 24,000 10 years ago, we could solve for the population decrease by using this expression:

24,000 × 0.02 = 480Why do we multiply by 0.02?

Well, if percentages are fractions of 100, this means that 2% is equivalent to [tex]\frac{2}{100}[/tex], which is also equivalent to 0.02.

This means over the past 10 years the population decreased by 480.

Now that we know this, we can subtract that from the total amount to get the population now.

24,000 - 480 = 23,520

This means that the population of the island now is 23,520.

Therefore, the population of the island now with a 2% decrease is 23,520.

many people use scanners to read documents and store them into pdf file. to help determine which brand of scanner to buy, a student conducts an experiment in which 8 different documents were scanned by each of the two scanners that he is interested in. he records the number of errors made by each. can he infer that brand a (the more expensive scanner) is better than brand b? that is, is the mean number of errors for brand a less than brand b? use brand a as population 1 and brand b as population 2. assume a 5% level of significance. dat

Answers

The student can use a two-sample t-test to determine if there is a significant difference between the mean number of errors made by brand A and brand B. The two-sample t-test compares the means of two populations to determine if they are significantly different from each other.

The null hypothesis for this test is that the mean number of errors for brand A is equal to the mean number of errors for brand B. The alternative hypothesis is that the mean number of errors for brand A is less than the mean number of errors for brand B.

To conduct the two-sample t-test, the student will need to calculate the mean and standard deviation of the number of errors for each brand. Then, he will use the t-test formula to calculate the t-value and compare it to the critical value for a 5% level of significance.

If the t-value is less than the critical value, the student can reject the null hypothesis and conclude that the mean number of errors for brand A is significantly less than the mean number of errors for brand B. This would suggest that brand A is better than brand B.

However, if the t-value is greater than the critical value, the student cannot reject the null hypothesis and cannot conclude that there is a significant difference between the two brands.

The length of QS in parallelogram RSTU is 7c - 1.

Describe Parallelogram?

A parallelogram is a quadrilateral with two pairs of parallel sides. This means that opposite sides of the parallelogram are parallel and have the same length. Additionally, opposite angles of a parallelogram are congruent, meaning they have the same measure.

Some important properties of parallelograms include:

Diagonals bisect each other: The diagonals of a parallelogram bisect each other. This means that the point where the diagonals intersect is the midpoint of each diagonal.

Opposite sides are congruent: The opposite sides of a parallelogram are congruent. This means that they have the same length.

Consecutive angles are supplementary: Consecutive angles of a parallelogram are supplementary, meaning they add up to 180 degrees.

Each pair of opposite sides is parallel: In a parallelogram, each pair of opposite sides is parallel. This means that the distance between the parallel sides is constant along the length of the parallelogram.

In a parallelogram, opposite sides are equal in length. Therefore, if we can find the length of TU, we can use it to find the length of QS.

To find TU, we can use the fact that SU and RT are diagonals that intersect at Q. Since diagonals of a parallelogram bisect each other, we know that QU = QT and QS = QS. Therefore, we can write:

TU = QU + QS = (c + 7) + (6c - 8) = 7c - 1

Now that we know TU, we can use it to find QS. Since QS = TU, we have:

QS = 7c - 1

Therefore, the length of QS in parallelogram RSTU is 7c - 1.

A standard number cube is rolled 150 times. Predict how many times it will roll a 1 or a 6.

Answers

Answer:

100 times

Step-by-step explanation:

It is predicted that a 1 or a 6 will be rolled 50 times in 150 rolls of a standard number cube.

A standard number cube has six faces, each numbered from 1 to 6.

The probability of rolling a 1 or a 6 on any given roll is,

P = 2/6

P = 1/3

Since, there are two favorable outcomes out of six possible outcomes.

Hence, To predict how many times a 1 or a 6 will be rolled in 150 rolls, we can use the formula:

Number of times = Probability x Total number of rolls

So, the number of times a 1 or a 6 is expected to be rolled in 150 rolls is:

Number of times = (1/3) x 150 = 50

Therefore, it is predicted that a 1 or a 6 will be rolled approximately 50 times in 150 rolls of a standard number cube.

The circumference of the hub cap of a tire is 74.04 centimeters. Find the area of this hub cap. Use 3.14 for pi.

Answers

Using the circumference, the area of the hub cap is obtained as approximately 437.21 square centimeters.

What is circumference?

The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area.

The circumference of the hub cap is given by the formula -

C = 2πr

where r is the radius of the hub cap.

We can solve for the radius by dividing both sides by 2π -

r = C / 2π

r = 74.04 / 2(3.14)

r ≈ 11.8 cm

The area of the hub cap is given by the formula -

A = πr²

Substituting the value of r in the equation, we get  -

A = π(11.8)²

A = 3.14 × 139.24

A ≈ 437.21 cm²

Therefore, the area of the hub cap is 437.21 square centimeters.
