d) Write a statement that correctly interprets the confidence interval Choose the correct answer below.
O A. One has 99% confidence that the sample proportion is equal to the population proportion
OB. 99% of sample proportions 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
OD. There is a 99% chance that the true value of the population proportion will fall between the lower
bound and the upper bound
