Question 1182738: Use the sample data and confidence level given below to complete part​ (a).
A drug is used to help prevent blood clots in certain patients. In clinical​ trials, among 4689 patients treated with the​ drug, 135 developed the adverse reaction of nausea. Construct a 99​% confidence interval for the proportion of adverse reactions.
a) Find the best point estimate of the population proportion p.

p hat=135/4689=0.02879. That is the best estimate or the point estimate.
99%CI half-interval is z(0.995)*sqrt(0.02879*0.97121/4689)
=0.00629
so the whole interval is (0.02250, 0.03508) or to three decimal places (0.023, 0.035)
