There is a 95% chance that the true value of the population proportion will fall between the lower bound and the upper bound OC One has 95% condidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion the population proportion OD. One has 96% confidence that the sample proportion is equal to Submit test Time Remaining:00 15.27 Next
