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=1085 and x=529 who said?"yes." Use a 90% confidence level.

a) Find the best point estimate of the population proportion p. D (Round to three decimal places as needed.) b) Identify the value of the margin of error E. E=D (Round to three decimal places as needed.) c) Construct the condence interval. awn (Round to three decimal places as needed.) d) Write a statement that correctly interprets the confidence interval. Choose the correct answer below. O A. One has 90% confidence that the sample proportion is equal to the population proportion. O B. One has 90% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion. O C. 90% of sample proportions will fall between the lower bound and the upper bound. O D. There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound
