(Round to three decimal places as needed.)
d) Write a statement that correctly interprets the confidence interval. Choose the correct answer below.
O A. 95% of sample proportions will fall between the lower bound and the upper bound.
O B. 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% confidence that the interval from the lower bound to the upper bound actually does contain the true value of the population proportion.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff2cc6f1c-7877-4946-8976-c24398bdb1a7%2Fc8022e38-f41e-4f3b-8c11-7dfdf44d65b5%2F7uoa88d.png&w=3840&q=75)
