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.

In clinical trials of the allergy medicine Clarinex (5 mg), it
was reported that 50 out of 1655 individuals in the Clarinex group
and 31 out of 1652 individuals in the placebo group experienced dry
mouth as a side effect of their respective treatments.
Test the hypothesis that a greater proportion of individuals in
the experimental group experienced dry mouth compared to the
individuals in the control group at the level of 5%
significance.

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...

In clinical trials of a medication, 2128 subjects were divided
into two groups. The 1585 subjects in group 1 received the
medication. The 543 in group 2 received a placebo. Of the 1585
subjects in group 1, 50 experienced dizziness as a side effect. In
group 2, 17 experienced dizziness as a side effect. To test
whether the proportion experiencing dizziness in group 1 is greater
than that in group 2, the researchers entered the data into
statistical software and...
