Preliminary data analyses indicate that you can consider the assumptions for using nonpooled t-procedures satisfied. Researchers randomly and independently selected 29 prisoners diagnosed with chronic posttraumatic stress disorder (PTSD) and 23 prisoners that were diagnosed with PTSD but had since recovered (remitted). The ages, in years, at arrest yielded the summary statistics shown in the table to the right. At the 10% significance level, do the data provide sufficient evidence to conclude that a difference exists in the mean age at arrest of prisoners with chronic PTSD and remitted PTSD? Chronic
