Time spent on homework is recognized as a strong correlate of juvenile problem behavior. The data below provide self-report substance use for a random sample of 8 youths who spend higher-than-average time on homework, and an independent random sample of 6 youths who spend lower-than-average time on homework. Using α = .10, test the hypothesis that spending more time on homework is associated with lower problem behavior. Show all five steps of your hypothesis test.
