Independent random samples of released prisoners in the fraud and firearms offense categories yielded the given information on time served, in months. At the 5% significance level, do the data provide sufficient evidence to conclude that the mean time served for fraud is less than that for firearms offenses? (Note: Xq = 10.71, s, = 4.86, X2 = 17.8, and $2 = 4.92.) EFEClick the icon to view the data table showing the time served for each offense.
