12. Clinical Trials of OxyContin OxyContin (oxycodone) is a drug used to treat pain, but it is well known for its addictiveness and danger. In a clinical trial, among subjects treated
with OxyContin, 52 developed nausea and 175 did not develop nausea. Among other subjects
given placebos, 5 developed nausea and 40 did not develop nausea (based on data from Purdue
Pharma L. P.). Use a 0.05 significance level to test for a difference between the rates of nausea
for those treated with OxyContin and those given a placebo.
a. Use a hypothesis test.
b. Use an appropriate confidence interval.
c. Does nausea appear to be an adverse reaction resulting from OxyContin?
