A university administrator was interested in determining if there was a difference in the distance students travel to get from c
eduard

Answer:

1) Fail to reject the Null hypothesis

2) We do not have sufficient evidence to support the claim that the mean distance students traveled to school from their current residence was different for males and females.

Step-by-step explanation:

A university administrator wants to test if there is a difference between the distance men and women travel to class from their current residence. So, the hypothesis would be:

H_{o}: \mu_{F}-\mu_{M}=0\\\\ H_{a}: \mu_{F}-\mu_{M}\neq 0

The results of his tests are:

t-value = -1.05

p-value = 0.305

Degrees of freedom = df = 21

Based on this data we need to draw a conclusion about test. The significance level is not given, but the normally used levels of significance are 0.001, 0.005, 0.01 and 0.05

The rule of the thumb is:

  • If p-value is equal to or less than the significance level, then we reject the null hypothesis
  • If p-value is greater than the significance level, we fail to reject the null hypothesis.

No matter which significance level is used from the above mentioned significance levels, p-value will always be larger than it. Therefore, we fail to reject the null hypothesis.

Conclusion:

We do not have sufficient evidence to support the claim that the mean distance students traveled to school from their current residence was different for males and females.

scoundrel [369]

Answer:  If the 40% off coupon is used, the subtotal will be $12.69

The gratuity would be exactly $4.23   (He will probably leave $4.25)

Step-by-step explanation: To find out the amount  of the discount

.40 × 21.15 = 8.46

To find the new subtotal, subtract  12.15 - 8.46 = 12.69

To figure the tip:  .20 × 21.15 = 4.23

Changing the percent to a decimal means divide the 20 by 100.

•To find :-

Area and perimeter of the circle.

• Solution :-

Let the radius of the circle be r cm.

Diameter = 8 cm.

We know,

★

So, Radius (r) = 8/2= 4 cm.

We know,

★

Area of circle= πr²

→Area of circle=

→Area of circle=

→Area of circle= 50.29(≈)cm²

____________________________

We know,

★

Perimeter of circle= 2πr

→ Perimeter of circle=

→Perimeter of circle=25.14(≈)cm
