(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. ts (Round to three decimal places as needed.) d) Write a statenment that correctly interprets the confidence interval. Choose the correct answer below. O A. 99% of sample proportions will fall between the lower bound and the upper bound. O B. There is a 99% chance that the true value of the population proportion will fall between the lower bound and the upper bound. O C. 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. D. One has 99% confidence that the sample proportion is equal to the population proportion.
