Number of Cigarettes 0 1-14 15-34 35 and more Smoked per Day Wear Seat Belts 223 19 28 12 Don't Wear Seat Belts 77 21 36 13 Use a 0.01 significance level to test the claim that the amount of smoking is independent of seat belt use. A plausible theory is that people who smoke are less concerned about their health and safety and are therefore less inclined to wear seat belts. Complete the following expected values table: Number of Cigarettes Smoked per Day 0 1-14 15-34 35 and more Row Total Wear Seat Belts Don't Wear Seat Belts Column Total The null and alternative hypotheses are: OA Ho: the amount of smoking is independent of seat belt use. Ha: the amount of smoking is dependent of seat belt use. B. Ho: the amount of smoking is dependent of seat belt use. H: the amount of smoking is independent of seat belt use. The statistic is: OA. Z (normal PDF) B. T (Student t-distribution) OC. X2 (Chi-Square distribution) whose value is: The critical value is: We take the decision to: A. Reject Ho B. Not reject Ho Therefore: A. Support H B. Do not Support H C. Does not apply Conclusion: A. At 1% significance level, there is sufficient evidence to reject the claim that the amount of smoking is independent of seat belt use. B. At 1 % significance level, there is not sufficient evidence to support the claim that the amount of smoking is independent of seat belt use. C. At 1% significance level, there is sufficient evidence to support the claim that the amount of smoking is dependent of seat belt use. OD.
