1. Which hypothesis test is most appropriate to determine if there is evidence to support the claim that the proportion of people who smoke is more than 19.0% ? a. Lower-tailed Z-test b. Two-tailed Z-test c. Upper-tailed Z-test d. Lower-tailed T-test e. Two-tailed T-test f. Upper-tailed T-test 2. Based on the answer to Q1, use the appropriate formula to compute the test statistic. "HINT" - THE SAMPLE CONTAINS A TOTAL OF 1200 PEOPLE, 242 OF WHICH SMOKE. (CONSIDER HOW YOU COULD GET THESE NUMBERS FROM THE DATA EASILY USING THE COUNTIF FUNCTION OR A PIVOT TABLE?) 3. Based on the answer to Q1, using the appropriate formula and a level of significance () of 0.05, compute the critical value. 4. Based on the results of Q3 and Q4, what is the conclusion of the hypothesis test? a. Fail to reject the null b. Reject the null 5. What does the result from Q4 mean "in English", i.e., what can we conclude based on the evidence available from the sample data? a. The proportion of people who smoke is significantly more than 19.0\%. b. The proportion of people who smoke is not significantly more than 19.0\%
