d) Write a statement that correctly interprets the confidence interval. Choose the correct answer below.
90%
of sample proportions will fall between the lower bound and the upper bound.There is a
90%
chance that the true value of the population proportion will fall between the lower bound and the upper bound.One has
90%
confidence that the sample proportion is equal to the population proportion.One has
90%
