point(s) possible A study recorded the cholesterol levels of more than 1400 participants in a certain city. To find a bootstrap confidence interval for the mean cholesterol, a student took 1000 bootstrap samples, calculated the mean of each, and found the following histogram of the bootstrap means. Complete parts a through c below. Click here to view the results from resampling. a) Use the data to construct a 95% confidence interval for the mean cholesterol. (Round to three decimal places as needed.) b) Interpret the interval you constructed in part a. Choose the correct answer be OA. 95% of all samples will have a mean cholesterol level within the confide OB. 95% of all people have a cholesterol level within the confidence interval OC. There is 95% confidence that a randomly selected person will have a ch D. There is 95% confidence that the true mean cholesterol level is within th c) What assumptions did you make, if any, in interpreting the interval? Select al A. It is assumed that the individual values in the sample were independent B. It is assumed that the population is nearly normal. C. It is assumed that the individual values in the sample were dependent. D. It is assumed that each bootstrap sample is nearly normal. E. No assumptions were made.
