Answer:

Accept the null hypothesis

Step-by-step explanation:

Two years ago, the average number of customers in your all of your company's stores per week was 3173 customers. Assume that you are doing a current study to test the claim that the mean weekly number of customers is different than it was two years ago.

The null hypothesis is:

[tex]H_{0} = 3173[/tex]

The alternate hypothesis is:

[tex]H_{A} \neq 3173[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

Due to our test, we have that [tex]\mu = 3173[/tex]

Assume a population standard deviation of 1,550 customers.

This means that [tex]\sigma = 1550[/tex]

Suppose you look at a random sample of 73 stores and find an average weekly customer total of 3,391.

This means that [tex]n = 73, X = 3391[/tex]

Test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{3391 - 3173}{\frac{1550}{\sqrt{73}}}[/tex]

[tex]z = 1.24[/tex]

p-value:

Since we are testing if the mean is different of a value, and the z-score is positive, the pvalue is 2 multiplied by 1 subtracted by the pvalue of z = 1.24.

z = 1.24 has a pvalue of 0.9251

2*(1 - 0.9251) = 2*0.0749 = 0.1498

0.1498 > 0.1, which means that we accept the null hypothesis, that is, that the mean weekly number of customers is equal to what it was two years ago at the 0.1 level of significance.

Answer:

y=-12x+20

Step-by-step explanation:

-4=-12(2) +b

-4=24+b

(add 24 both sides)

20=b

slope: -12

y intercept: (0,20)

Answer:

y + 4 = -12(x - 2)

Step-by-step explanation:

Use the point-slope formula for the equation of a straight line:

y - k = m(x - h)

Here m = -12, h = 2 and k = -4, and so we have:

y + 4 = -12(x - 2)

Step-by-step explanation:

Answer:

The edge length is 3/4

Step-by-step explanation:

Given

Shape: Cube

[tex]Volume = 27/64[/tex]

Required

Determine the edge length

Let the edge length be l.

So:

[tex]Volume=l^3[/tex]

Substitute 27/64 for Volume

[tex]27/64=l^3[/tex]

Express as exponent og 3

[tex]3^3/4^3 = l^3[/tex]

Apply indices rule

[tex](3/4)^3 = l^3[/tex]

Take cube root of both sides

[tex]3/4 = l[/tex]

[tex]l =3/4[/tex]

Answer:

3/4

Step-by-step explanation: try dividing because 4 is able to reach 64 and 3 can go to 27

Answer:

8,10,12

Step-by-step explanation:

Answer:

integer 1 = 8

integer 2 = x+2 = 8+2 = 10

integer 3 = x+4 = 8+4 = 12

Step-by-step explanation:

integer 1 = x , smallest

integer 2 = y , x+12

integer 3 = z , largest, x+4

three times the smallest is twice the largest.

3 (x) = 2 (x+4)

solve for x:

3x = 2x + 8

3x-2x = 8

x = 8

Replacing:

integer 1 = 8

integer 2 = x+2 = 8+2 = 10

integer 3 = x+4 = 8+4 = 12

Answer:

It's 3 and 177.

Step-by-step explanation:

Let the angle be x°. Then its supplementary is 59x°.

We know,

x+ 59x=180

or, x = 3°

and another angle, 59x°= 177°

Step-by-step explanation:

because the outer line is one line and the triangle in other line

Answer:

3

Step-by-step explanation:

There is a line of symmetry from each vertex of the triangle through the square opposite it. I can't draw it out here but there's one going straight down the middle, another going from the triangles leftmost point through the right hand square and another from the triangles rightmost point through the left hand square.
