Question: Many studies have been conducted to test the effects of marijuana use on mental abilities. In one such study, groups of light and heavy users of marijuana in college were tested for memory recall, with the results given below (based on data from "The Residual Cognitive Effects of Heavy Marijuana Use in College Students," by Pope and Yurgelun-Todd, Journal of the American Medical Association, Vol. 275, No. 7). Report the p-value for the test. Use = 0.01 to test the claim that the population of heavy marijuana users has a lower mean than the population of light marijuana users.
