A 95% confidence interval of 16.0 months to 51.2 months has been found for the mean duration of imprisonment, μ, 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 = 45 months.) d. Find a 99% confidence interval for the mean duration of imprisonment, μ, if a sample of the size determined in part (c) has a mean of 36.3 months. a. The margin of error is (Type an integer or a decimal.) months. ---
