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 4330 patients treated with the​ drug,121 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 proportionp.
​(Round to three decimal places as​ needed.)
b) Identify the value of the margin of error E.
E = ?
​(Round to three decimal places as​ needed.)
c) Construct the confidence interval.
? < p < ?
​(Round to three decimal places as​ needed.)
​d) Write a statement that correctly interprets the confidenceinterval. Choose the correct answer below.
A.One has 99​% confidence that the interval from the lower boundto the upper bound actually does contain the true value of thepopulation proportion.
B.One has 99​% confidence that the sample proportion is equal tothe population proportion.
C. 99​% of sample proportions will fall between the lower boundand the upper bound.
D.There is a 99​% chance that the true value of the populationproportion will fall between the lower bound and the upperbound.
