<p<]
(Round to three decimal places as needed.)
d) Write a statement that correctly interprets the confidence interval. Choose the correct answer below.
O A. 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.
B. One has 95% confidence that the sample proportion is equal to the population proportion.
C. There is a 95% chance that the true value of the population proportion will fall between the lower bound and the upper bound.
D. 95% of sample proportions will fall between the lower bound and the upper bound.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F66ac5d0d-fc89-4c09-8186-ee5bac8ff70c%2Fce971ae0-20d1-45b9-b660-c42d16049dd6%2Fy7ydftr_processed.png&w=3840&q=75)
