Choose the correct answer below. O A. 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. OB. There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound. O C. 90% of sample proportions will fall between the lower bound and the upper bound. OD. One has 90% confidence that the sample proportion is equal to the population proportion.
