Preliminary data analyses indicate that the assumptions for using pooled t-procedures are satisfied. Independent random samples of released prisoners in the fraud and firearms offense categories yielded the given information on time served, in months. At the 1% significance level, do the data provide sufficient evidence to conclude that the mean time served for fraud is less than that for firearms offenses?
