Preliminary analyses indicate that you can consider the assumptions for using nonpooled

Preliminary analyses indicate that you can consider the assumptions for using nonpooled t-procedures satisfied Researchers randomly and independently selected 30 prisoners diagnosed with chronic posttraumatic stress disorder (PTSD) and 23 prisoners that were diagnosed with PTSD but had since recovered (remitted). Chronic 7 = 26.7 = 4 n = 30 Remitted X = 23.5 $ = 9 " = 23 Obtain a 95% confidence interval for the difference, -, between the mean ages at arrest for prisoners with chronic PTSD and remitted PTSD.
