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