Use the sample data and confidence level given below to complete parts (a) through (d). A research institute poll asked respondents if they acted to annoy a bad driver. In the poll, n= 2673, and x= 1061 who said that they honked. Use a 99% confidence level. n3D Click the icon to view a table of z scores. (Round to three decimal places as needed.) b) Identify the value of the margin of error E. D E = (Round to four 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. O A. There is a 99% chance that the true value of the population proportion will fall between the lower bound and the upper bound. O 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. O D. One has 99% confidence that the sample proportion is equal to the population proportion.
