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 = 969 and x = 545 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. E=0 (Round to three decimal places as needed.). c) Construct the confidence interval. 0

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 = 969 and x = 545 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. 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. 90% of sample proportions will fall between the lower bound and the upper bound. 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. 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.
