2. Suppose you wish to test the effect of Prozac on the well-being of depressed individuals, using a standardized "well-being scale" whose values could range from 0 to 20. Higher scores indicate greater well-being (that is, Prozac is having a positive effect), where lower values show a lower well-being. The table below shows mood pre and post taking the drug. Subject Mood-Pre Mood-Post Subject Mood-Pre Mood-Post 1 3 5 6 6 9 2 7 7 U N 8 11 AW 9 4 8 5 4 8 10 3 Perform a paired t-test to determine if the mean well-being score before taking Prozac is significantly different than the mean well being score after. Test at a 1% level of significance. 2. Paired t- test Decision Rule: We will reject the Null Hypothesis, Ho, if the testing Null Hypothesis: H : H =0 statistic is Alt. Hypothesis: H : HD 0 Number of pairs: n = Mean Difference: d = I.5. = d - up = 50 = Vn p-value= Result of test : dfen - 1= Final Conclusion: Based on the given information... (n is the # of pairs of data)
