Use the sample data and confidence level given below to complete parts​ (a) through​ (d). A research institute poll asked respondents if they felt vulnerable to identity theft. In the​ poll, n=955 and x=506 who said​ "yes." Use a 99% confidence level. ​A. Find the best point estimate of the population proportion p. ? B. Identify the value of the margin of error E. E = ? C. Construct the confidence interval. ? < p < ? D. Write a statement that correctly interprets the confidence interval. Choose the correct answer below. Which Letter is correct? a) 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.   b) There is a 99​% chance that the true value of the population proportion will fall between the lower bound and the upper bound.   c) 99​% of sample proportions will fall between the lower bound and the upper bound.   d) One has 99​% confidence that the sample proportion is equal to the population proportion.

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.
