Preliminary analyses indicate that you can consider Chronic Remitted the assumptions for using nonpooled t-procedures satisfied. Researchers randomly and independently x1 = 25.8 X2 = 22.1 selected 27 prisoners diagnosed with chronic S1 = 3 $7 = 4 posttraumatic stress disorder (PTSD) and 21 prisoners that were diagnosed with PTSD but had n1 = 27 n2 = 21 since recovered (remitted). Obtain a 90% confidence interval for the difference, H1 - H2, between the mean ages at arrest for prisoners with chronic PTSD and remitted PTSD. . . . The 90% confidence interval is from to (Round to three decimal places as needed.)
