A new study on the widely used antidepressant AD+ has been published. The study has information on the side effects of the drug. For each of the 15 randomly chosen users of AD+ who participated in the study, a score from 0 to 100 was assigned according to the severity and variety of side effects from the drug (a score of 0 meant no side effects). A similar assessment was made for 29 independently and randomly chosen users of the competitor antidepressant XAD24. The data are summarized in the following table: XAD24 users AD+ usersS X = 49 x2= 54.8 s = 204.49 s= 110.25 (The first row gives the sample means and the second row gives the sample variances.) Assume that the populations of side effect scores for each of the drugs are approximately normally distributed. Can we conclude, at the 0.1 significance level, that the variance of scores for all AD+ users, o, is different from the variance of scores for all XAD24 users, 0? Perform a two-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.)
