For questions 7-12, refer to the following information:Much discussion has appeared in the medical literature in recent year on the role of intermittent fasting on BMI. In a research study, investigators compared the mean BMI of 24 individuals aged 20-29 who had been intermittent fasting for the past 6 months. The mean BMI was 24.6 with a standard deviation of 4.3. If the mean BMI for the general population is 26.5, using a 0.01 significance level, test the claim that the group of people who intermittent fast have a BMI that is different from those of the general population.

Q 7

Question 7

What is the null hypothesis H0?(1 point)

Select one:

a.x=26.5

b.x26.5

c.=26.5

d.26.5

e. None of the above because we need to compare the population mean to 24.6

Q 8

Question 8

What is the alternative hypothesis H1?(1 point)

Select one:

a.x=26.5

b.x26.5

c.=26.5

d.26.5

e. None of the above because we need to compare the population mean to 24.6

Q 9

Question 9

What critical value should you use to test the given hypothesis?(2 points)

Select one:

a. 2.807

b. 2.069

c. 2.500

d. 2.831

e. 2.797

f. None of the above because we only need 1 critical values (one positive and no negative)

Q 10

Question 10

What is the value of the test statistic you should use to test the given hypothesis?(2 points)

Select one:

a. 10.41

b. 2.16

c. -2.16

d. -10.41

e. -13.45

Q 11

Question 11

What conclusion should you make based on the given data?(1 point)

Select one:

a. Reject H0and conclude there is sufficient evidence to support the claim that this sample comes from a population that is different than a BMI of 26.5.

b. Reject H0and conclude there is not sufficient evidence to support the claim that this sample comes from a population that is different than a BMI of 26.5.

c. Accept H0and conclude there is sufficient evidence to support the claim that this sample comes from a population that is different than a BMI of 26.5

d. Fail to reject H0and conclude there is sufficient evidence to support the claim that this sample comes from a population that is different than a BMI of 26.5.

e. Fail to reject H0and conclude there is not sufficient evidence to support the claim that this sample comes from a population that is different than a BMI of 26.5.

Q 12

Question 12

Select one:

a. -2.518

b. -2.508

c. -2.500

d. 2.500

e. 2.508

f. 2.518
