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 = 1060 and x=501 who said "yes" Use a 90% confidenc Click the icon to view a table of z scores. a) Find the best point estimate of the population proportion p. 0.473 (Round to three decimal places as needed) b) Identify the value of the margin of error E Ex (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. D A. One has 90% confidence that the sample proportion is equal to the population proportion. OB. 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 OC. 90% of sample proportions will fall between the lower bound and the upper bound Themifina chent that the lako rading will fall bakunan the nur hand and the unnar hund
0.473 (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 P (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 sample proportion is equal to the population proportion OB. 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 OC. 90% of sample proportions will fall between the lower bound and the upper bound OD. There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound
