Find t, Z, P

Preliminary data analyses indicate that you can consider the assumptions for using nonpooled t-procedures satisfied. Researchers randomly Chronic Remitted and independently selected 30 prisoners diagnosed with chronic posttraumatic stress disorder (PTSD) and 24 prisoners that were diagnosed X1 = 27.8 X2 = 22.2 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 5% significance level, do the data provide sufficient evidence to conclude that a difference exists in the mean age at arrest of prisoners S1 = 4 $2 = 9 with chronic PTSD and remitted PTSD? 01 = 30 n2 = 24 What are the hypotheses for the nonpooled t-test?
