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 clinicaltrials, among 4990 patients treated with thedrug, 130 developed the adverse reaction of nausea.

Construct a 99% confidence interval for the proportion of adverse reactions.

1) Find the best point estimate of the population proportion p________ (Round to three decimal places asneeded.)

2) Identify the value of the margin of error E______________ (Round to three decimal places asneeded.)

3) Construct the confidence interval._______< p < ________ (Round to three decimal places asneeded.)

4) Write a statement that correctly interprets the confidence interval. Choose the correct answer below.

A. One has 99% confidence that the sample proportion is equal to the population proportion.

B. One has 99% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion.

C. There is a 99% chance that the true value of the population proportion will fall between the lower bound and the upper bound.

D. 99% of sample proportions will fall between the lower bound and the upper bound.
