Use the sample data and confidence level given below to complete parts​ (a) through​ (d). In a study of cell phone use and brain hemispheric​ dominance, an Internet survey was​ e-mailed to 2397 subjects randomly selected from an online group involved with ears. 1025 surveys were returned. Construct a 99​% confidence interval for the proportion of returned surveys. LOADING...

Choose the correct answer below. A. There is a 99​% chance that the true value of the population proportion will fall between the lower bound and the upper bound. B. 99​% of sample proportions will fall between the lower bound and the upper bound. C. One has 99​% confidence that the sample proportion is equal to the population proportion. D. 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.
