(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. 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 C. One has 99% confidence that the sample proportion is equal to the population proportion. O D. 99% of sample proportions will fall between the lower bound and the upper bound
