(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 (Round to three decimal places as needed.) d) Write a statement that correctly interprets the confidence interval. Choose the correct answer below. OA. 90% of sample proportions will fall between the lower bound and the upper bound 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. One has 90% confidence that the sample proportion is equal to the population proportion OD. There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound
