Use the sample data and confidence level given below to complete parts (a) through (d). A drug is used to help prevent blood clots in certain patients. In clinical trials, among 4939 patients treated with the drug, 166 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. (Round to three decimal places as needed.)

Expert Solution
Step 1

Given
Total number of patients treated with drug = n = 4939
The total number of patients developed the adverse reaction of nausea = 166
The proportion of patients developed the adverse reaction of nausea = p = 166/4939 = 0.0336

The value of n*p and n(1-p) are 166 and 4773 both are more than 10, so we assume normal approximation as the sample size is large.

The 99% critical Z value is 2.575

The point estimate = p = 0.0336
