    B. There is a 90 % chance that the true value of the population proportion will fall between the lower bound and the upper bound.

    Step-by-step explanation:

    A. One has 90 % confidence that the sample proportion is equal to the population proportion.

    Confidence interval gives an interval estimate, not an equality

    B. There is a 90 % chance that the true value of the population proportion will fall between the lower bound and the upper bound.

    Ture.

    C. 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.

    Also true but One has 90 % confidence is not good interpretation.

    D. 90 % of sample proportions will fall between the lower bound and the upper bound.

    Lower bound and upper bound is given to estimate population proportion.
