A drug is used to help prevent blood clots in certain patients. In clinical​ trials, among 45514551 patients treated with the​ drug, 149149 developed the adverse reaction of nausea. Construct a 9090​% confidence interval for the proportion of adverse reactions. ​a) Find the best point estimate of the population proportion p. ​b) Identify the value of the margin of error E ​c) Construct the confidence interval. d) Write a statement that correctly interprets the confidence interval. Choose the correct answer below.     A. There is a 9090​% chance that the true value of the population proportion will fall between the lower bound and the upper bound.   B. One has 9090​% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion.   C. One has 9090​% confidence that the sample proportion is equal to the population proportion.   D. 9090​% of sample proportions will fall between the lower bound and the upper bound.

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
