Preliminary data analyses indicate that you can consider the assumptions for using nonpooledt-procedures satisfied. Researchers randomly and independently selected 31

prisoners diagnosed with chronic posttraumatic stress disorder(PTSD) and 21 prisoners that were diagnosed with PTSD but had since recovered(remitted). Theages, inyears, at arrest yielded the summary statistics shown in the table to the right. At the 10% significancelevel, do the data provide sufficient evidence to conclude that a difference exists in the mean age at arrest of prisoners with chronic PTSD and remittedPTSD?

Find the test statistic.

t=_____?

(Round to three decimal places asneeded.)

Find theP-value.

P=______?

(Round to four decimal places asneeded.)
