Part 4
d) Write a statement that correctly interprets the confidence interval. Choose the correct answer below.
99%
of sample proportions will fall between the lower bound and the upper bound.One has
99%
confidence that the sample proportion is equal to the population proportion.There is a
99%
chance that the true value of the population proportion will fall between the lower bound and the upper bound.One has
99%
confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion.Expert Solution
