A study of 6 different weight loss programs involved 120 subjects. Each of the 6 programs had 20 subjects in it. The subjects were followed for 12 months. Weight change for each subject was recorded. We want to test the claim that the mean weight loss is the same for the 6 programs. (a) Complete the following ANOVA table with sum of squares, degrees of freedom, and mean square (Show all work): Source of Variation Sum of Squares (SS) Degrees...

4) A study of depression and exercise was conducted. A total of 5 groups were used: each group differs by the extent to which group members exercise. A depression rating (scale: 1-100, a continuous variable) was given to all 1215 participants in the sample. An incompleted ANOVA table is provided below.
