Answer: statistically significant

Step-by-step explanation:

The p-value of a statistical test tell us the conclusion to our hypothesis. When the result of the p-value lies between 0.27 it means there is a 27% chance of it occurring, when it is at 0.02 it means there is a 2% chance of it occurring. When it lies between 0.0027 it means there is 0.27 chance of it occurring this becomes statistically significant as this won’t have much changes or effects on the hypothesis. So what this means is there is chance it won’t occur.

Its c/2

Answer: (a) 10 (b) 1. 10 2. -10 (c) 1. 10 2. 10

Step-by-step explanation:

Answer: -20

Step-by-step explanation:

2(-3 -7)

Use distributive property

2 * -3 = -6

2 * -7 = -14

-6 -14

Then, combine them

-6 -14 = -20

Answer:

-20

Step-by-step explanation:

Given:

The ratio of the measures of the angles of a triangle is 1:2:3.

To find:

The measures of each angle​.

Solution:

Let the measure of angles be x, 2x and 3x respectively.

We know that, sum of all the interior angles of a triangle is 180 degrees by the angle sum property.

Using angle sum property, we get

[tex]x+2x+3x=180^\circ[/tex]

[tex]6x=180^\circ[/tex]

Divide both sides by 6.

[tex]x=\dfrac{180^\circ}{6}[/tex]

[tex]x=30^\circ[/tex]

Now,

First angle: [tex]30^\circ[/tex]

Second angle: [tex]2(30^\circ)=60^\circ[/tex]

Third angle: [tex]3(30^\circ)=90^\circ[/tex]

Therefore, the measure of all the angles are 30°, 60° and 90° respectively.

Answer:

This explanation is not correct

Explanation:

Significance level is the probability that the null hypothesis rejected is in fact true. If we say there is a significance level of 0.10 or 10%(α=0.10 level) then there is a 10% chance of incorrectly rejecting the null hypothesis when there is actually no difference.

If we wish to reach a conclusion on rejection or acceptance of the null hypothesis, we could use the p value(the probability that observed results or more extremee results are true given null hypothesis)which we compare with the significance level to conclude. If the significance level is 0.10 and p value is 0.07(since p value is less than significance level) , we reject the null hypothesis and vice versa.

The significant level, α = 0.05 level specifies a probability of the correctness of the null hypothesis.

Reasons:

The significant level specifies the the likelihood of rejecting a true null

hypothesis, such that a 5% significance level indicates that the risk of

drawing a conclusion that there is a difference in a sample, when the

samples are similar is 5%, and therefore, the probability that null

hypothesis is true is 5% or 0.05.

The level of significance is a specification that indicates the amount of

evidence required within a sample to allow the rejection of the null

hypothesis, and reach a conclusion that the observed effect is statistical

significant at the α = 0.05 level.

Therefore;

The statement by the student that "This means that the probability that the null hypothesis is true is less than 0.05" is correct.

Answer:

[tex]N = 5040[/tex]

Step-by-step explanation:

Required

Arrange the letters of "sleepless"

First, we count the number (n) of characters

[tex]n = 9[/tex]

First, we count the number (n) of repeated characters

[tex]s = 3[/tex]

[tex]e = 3[/tex]

[tex]l = 2[/tex]

The arrangement (N) is then calculated as follows;

[tex]N = \frac{n!}{s!e!l!}[/tex]

This gives:

[tex]N = \frac{9!}{3!3!2!}[/tex]

[tex]N = \frac{9*8*7*6*5*4*3*2*1}{3*2*1*3*2*1*2*1}[/tex]

[tex]N = \frac{362880}{72}[/tex]

[tex]N = 5040[/tex]

Hence, there are 5040 distinct arrangements

Step-by-step explanation:

Hi there!

[tex]\large\boxed{x = \frac{3}{4}, y = \frac{9}{4}}}[/tex]

8x + 4y = 15

x + y = 3

Use the second equation to solve for a particular variable since it is easier to isolate. We can begin by solving for y:

x + y = 3

Subtract y from both sides:

x = -y + 3

Substitute in this expression for x into the other equation:

8(-y + 3) + 4y = 15

Distribute and simplify:

-8y + 24 + 4y = 15

-4y + 24 = 15

-4y = -9

y = 9/4

Substitute in this value of y to solve for x:

8x + 4(9/4) = 15

8x + 9 = 15

8x = 6

x = 6/8 = 3/4

The values respectively are:

x = 3/4, y = 9/4
