A study of seat belt users and nonusers yielded the randomly selected sample data summarized in the accompanying table. Use a 0.05 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 arc less concerned about their health and safety and are therefore less inclined to wear seat belts. Is this theory supported by the sample data?
