A researcher hopes to demonstrate that her Interpersonal Psychotherapy (IPT) is more effective than Cognitive Behavior Therapy (CBT) in reducing Beck Depression Inventory (BDI) scores. She predicts that the IPT group will have lower scores than the CBT. She randomly assigns 25 depressed patients to each treatment and her results are summarized below. Use alpha = .05 for the following questions. СВТ IPT X = 26 X = 21 S1 = 4 S2 = 3 ni= 25 n2 = 25
