According to a study of political prisoners, the mean duration of imprisonment for 34 prisoners with chronic post-traumatic stress disorder (PTSD) was 34.4 months. Assuming that a = 37 months, determine a 95% confidence interval for the mean duration of imprisonment, μ, of all political prisoners with chronic PTSD. Interpret your answer in words. Click here to view Page 1 of the table of areas under the standard normal curve. Click here to view Page 2 of the table of areas under the standard normal curve. A 95% confidence interval for the population mean is from months to months. (Round to one decimal place as needed.)
