Question

Application Questions 1. The following data are from an independent-measures experiment comparing two different behavioral regimens for the treatment of depression. In treatment condition A, participants take part in a program to increase exercise and restrict a high-fat diet. Participants in Treatment condition B, change only their diet. Researchers predict that the participants in Treatment A will have higher happiness scores. Does the data below indicate a significant advantage for diet and exercise programs in treating depression? Treatment A: 13, 9, 7, 11 Treatment B: 9, 5, 5, 9 a. Step 1: State the hypotheses ($H_0$ and $H_a$). b. Step 2: Set the criteria for a decision ($t_{crit}$). c. Step 3: Compute the statistic ($t_{obt}$). d. Step 4: Make a decision. e. Compute $p_b$.
