Preliminary analyses indicate that you can consider the assumptions for using nonpooled t-procedures satisfied. Researchers randomly and independently selected 28 prisoners diagnosed with chronic posttraumatic stress disorder (PTSD) and 22 prisoners that were diagnosed with PTSD but had since recovered (remitted). Obtain a 95% confidence interval for the difference, ₁-₂ between the mean ages at arrest for prisoners with chronic PTSD and remitted PTSD. The 95% confidence interval is from to (Round to three decimal places as needed.). Chronic = 26.3 X₁ S₁ = 2 n₁ = 28 Remitted = 24.2 $2 = 6 n₂ = 22
