Sunny County is studying the relationship of gender and various college activities in the county including college undergraduate drinking. You survey 243 students and ask them to self-rate themselves on a 33-point drinking scale (higher score means more self-reported drinking). You suspect that the reported undergraduate mean male drinking scale will be higher than females. In your sample, 134 females reported a mean of 17.31 on the drinking scale (with a standard deviation of 6.34) and 109 males reported a mean of 21.31 on the drinking scale (with a standard deviation of 6.55).
