Follow-up Question

I think the answer to this last part is C

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=944 and x = 504 who said "yes." Use a 99% confidence level. Click the icon to view a table of z scores. E = 0.042 (Round to three decimal places as needed.) c) Construct the confidence interval. BELEID 0.492 <p< 0.576 (Round to three decimal places as needed.) d) Write a statement that correctly interprets the confidence interval. Choose the correct answer below. OA. There is a 99% chance that the true value of the population proportion will fall between the lower bound and the upper bound. B. 99% of sample proportions will fall between the lower bound and the upper bound. OC. 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. OD. One has 99% confidence that the sample proportion is equal to the population proportion.
