Preliminary analyses indicate that you can consider the assumptions for using nonpooled t-procedures satisfied. Researchers randomly and independently selected 27 prisoners diagnosed with chronic posttraumatic stress disorder (PTSD) and 24 prisoners that were diagnosed with PTSD but had since recovered (remitted). Chronic X₁ = 29.2 S₁ = 3 n₁ = 27 The 90% confidence interval is from to (Round to three decimal places as needed.) Remitted X2 $2 n₂ = 24.7 = 5 = 24 Obtain a 90% confidence interval for the difference, ₁-2, between the mean ages at arrest for prisoners with chronic PTSD and remitted PTSD.
