Determine the null hypothesis, alternative hypothesis, student's t calculation, critical region (see t distribution table, use the two-tailed level of significance) and decision and the conclusions that can be reached with this test. In a study that evaluated the effect of cognitive behavioral therapy as an adjuvant in the treatment of people with major depression. Two groups of 21 patients diagnosed with major depression were assessed with the Beck Depression Inventory. One group of people were treated with cognitive behavioral therapy for two weeks as an add-on to their fluoxetine treatment, while the other group only received their fluoxetine treatment (without receiving cognitive behavioral therapy). The scores on the Beck Depression Inventory are as follows: No cognitive behavioral therapy 28 55 31 60 35 21 59 44 59 23 27 54 37 20 20 35 44 32 61 26 59 With cognitive behavioral therapy 20 20 21 21 19 14 20 15 27 22 17 30 14 17 22 26 18 18 23 17 14
