According to a study of political prisoners, the mean duration of imprisonment for 36 prisoners with chronic post-traumatic stress disorder (PTSD) was 31.2 months. Assuming that o = 45 months, determine a 90% confidence interval for the mean duration of imprisonment, μ, of all political prisoners with chronic PTSD. Interpret your answer in words.
