Use the sample data and confidence level given below to completeparts (a) through (d).
A drug is used to help prevent blood clots in certain patients.In clinical trials, among
4102
patients treated with the drug,
123
developed the adverse reaction of nausea. Construct a
99%
confidence interval for the proportion of adverse reactions.
