Extracted text: 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=990 and x= 510 who said "yes " Use a 95% confidence level. Click the icon to view a table of z scores. a) Find the best point estimate of the population proportion p. (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. (Round to three decimal places as needed.) d) Write a statement that correctly interprets the confidence interval. Choose the correct answer belc O A. 95% of sample proportions will fall between the lower bound and the upper bound O B. One has 95% confidence that the sample proportion is equal to the population proportion O C. One has 95% confidence that the interval from the lower bound to the upper bound agtualy does contain the true Malue of the population proportion. There is a 95% chance that the true value of the population proportion will fall between the lower bound and thelupper bound.
