Question
↑ 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=1004 and x 517 who said "yes." Use a 90% 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 (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 below OA. 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 OB. One has 90% confidence that the sample proportion is equal to the population proportion OC. There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound. OD. 90% of sample proportions will fall between the lower bound and the upper bound
