Zoloft is a drug used to treat obsessive-compulsive disorder (OCD). In randomized, double-blind clinical trials, 926 patients diagnosed with OCD were randomly divided into two groups. Subjects in group 1 (experimental group) received 200 milligrams per day (mg/day) of Zoloft, while subjects n group 2 (control group) received a placebo. Of the 553 subjects in the experimental group, 77 experienced dry mouth as a side effect. Of the 373 subjects in the control group, 34 experienced dry mouth as a side effect. Do a higher proportion of subjects experience dry mouth who are taking Zoloft versus the proportion taking the placebo? Use the α = 0.01 level of significance. Use the p-value approach.

Researchers conducted a randomized, double-blind study to measure the effects of the drug olanzapine on patients diagnosed with bipolar disorder. A total of 115 patients with a DSM-IV diagnosis of bipolar disorder were randomly divided into two groups. Group 1 (n1 = 55) received 5 to 20 mg per day of olanzapine, while group 2 (n2 = 60) received a placebo. The effectiveness of the drug was measured using the Young–Mania rating scale total score with the net improvement in...
