Choosethe correct answer below. A. One has 90​% confidence that theinterval from the lower bound to the upper bound actually doescontain the true value of the population proportion. B. 90​% ofsample proportions will fall between the lower bound and the upperbound. C. One has 90​% confidence that the sample proportion isequal to the population proportion. D. There is a 90​% chance thatthe true value of the population proportion will fall between thelower bound and the upper bound.
