Question

The article “Wired: Energy Drinks, Jock Identity, Masculine Norms, and Risk Taking” (K. Miller, Journal of American College Health, 2008:481–489) reports that in a sample of 413 male college students, the average number of energy drinks consumed per month was 2.49 with a standard deviation of 4.87, and in a sample of 382 female college students, the average was 1.22 with a standard deviation of 3.24. Can you conclude that the mean number of energy drinks is greater for male students than for female students?
