A recent survey collected data from American police officers, including data about the officers' personal marijuana use history. Out of 919 sheriff's deputies, 390 reported having used marijuana at least once in their life. Out of 332 state troopers, 122 reported having used marijuana at least once in their life. Use this information to test the hypothesis that the proportion of sheriff's deputies who have used marijuana at least once is greater than the proportion of state troopers who have used marijuana at least once. Use = .05. a. Are the sample sizes large enough for formulas based on the CLT to work? b. What are the null and alternative hypotheses for this test? c. What is the sample statistic of interest? Provide notation and value. d. Use the formula based on the CLT to find the Z Test Statistic. (HINT: Remember to calculate the SE using pooled proportions!) e. Use the Z Test Statistic and StatKey to find the p-value. f. Rule on Ho and interpret the results within the context of the example
