Question: a) Researchers are interested in finding out the best way for people to lose weight. They obtain 30 students who are interested in losing weight; they agree to participate in the study. Participants are randomly assigned to 1 of 3 groups: a diet group, an exercise group, and a behavior modification group. After 1 month, researchers recorded the number of pounds lost by each participant. Use α = .05 to determine if there are any differences in weight loss between the 3 groups.

b) Compute Tukey’s test to for the pairwise if necessary.

c) Compute R2

Diet: 2 3 2 4 0 1 2 3 2 1

Exercise: 0 1 0 3 1 2 1 2 3 0

Behavior Modification: 6 3 4 5 4 7 3 5 6 7
