A 95% confidence interval of 19.1 months to 48.7 months has been found for the mean duration of imprisonment, u, of political prisoners of a certain country with chronic PTSD. a. Determine the margin of error, E. b. Explain the meaning of E in this context in terms of the accuracy of the estimate. c. Find the sample size required to have a margin of error of 12 months and a 99% confidence level. (Use o =42 months.) d. Find a 99% confidence interval for the mean duration of imprisonment, u, if a sample of the size determined in part (c) has mean of 36.2 months. a. The margin of error is (Type an integer or a decimal.) months. b. Choose the correct answer below. O A. One can be 95% confident that the maximum error made in estimating u by x is as found in part (a). O B. One can be 95% confident that the minimum error made in estimating u by x is as found in part (a). O C. One can be 95% confident that the interval 19.1 months to 48.7 months contains the mean duration of imprisonment, u, of the prisoners. O D. The average duration of imprisonment is as found in part (a). c. The required sample size to have a margin of error of 12 months with a 99% confidence level is (Round up to the nearest whole number.) prisoners. d. The 99% confidence interval for the mean duration of imprisonment, u, is from months to months. (Round to one decimal place as needed. Use ascending order.) y is

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative p…
