Question 1 of 4

For which of the following would it be most appropriate to use an ANOVA to analyze the data?

A researcher wants to compare which weight loss strategy works the best: a) body appreciation mindfulness techniques b) plant based meal prep or c) both body appreciation mindfulness techniques and plant based meal prep. They randomly assign 60 participants to one of the three categories and then asks them if they felt the method was effective (yes/no) after a period of 6 months.

A researcher wants to compare which weight loss strategy works the best: a) body appreciation mindfulness techniques b) plant based meal prep or c) both body appreciation mindfulness techniques and plant based meal prep. They randomly assign 60 participants to one of the three categories and then track their weight loss in pounds over a period of 6 months.

Both A and B.

Neither A nor B.

Please use the following information for Questions 2, 3, and 4.

To determine whether there was a relationship between the region of the world that you live in and the amount of beer that you drink, suppose we took 3 samples of 25 people per region from Asia, Europe and America.

Question 2 of 4

If we let 1, 2, and 3be the average beer per capita in liters for Asia, Europe and America, respectively, the appropriate hypotheses in this case are:

H0: 1= 2= 3Ha: 1, 2, 3, are not all equal

H0: 1, 2, 3, are not all equalHa: 1= 2= 3

H0: 1= 2= 3Ha: 1 2 3

H0: 1 2 3Ha: 1= 2= 3

None of the above are correct.

Question 3 of 4

Here are the three sample standard deviations for the beer consumption for the three groups (Asia, Europe and America):

Based on this information, do the data meet the condition of equal population standard deviations for the use of the ANOVA?

Yes, because 7.3 - 5.2 < 2.

Yes, because7.3

No, because the standard deviations are not equal.

No, because 7.3 - 5.2 > 2.

No, because the standard deviations are not equal.

Unable to determine from the information provided.

Based on this information, we :

Fail to reject the H0and conclude that the data provide strong evidence that the three means (representing the amount per capita of beer that people drink per region) are not all equal.

Fail to reject the H0and conclude that the data do not provide sufficient evidence that there is a relationship between the the region of the world and the quantity of beer that people drink.

Reject the H0and conclude that the data provide strong evidence that there is a relationship between the region of the world and the quantity of beer that people drink.

Reject the H0and conclude that the data provide strong evidence that the amount of beer people drink is related to region the following way: the mean for Europe is higher than the mean for America, which in turn is higher than that of Asia.
