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 theory is that people who smoke are less concerned about their health and safety and are therefore less inclined to wear seat belts. Is this theory supported by the sample data? E Click the icon to view the data table. Determine the null and alternative hypotheses. O A. Hg: Heavy smokers are not less likely than non-smokers to wear a seat belt. H: Heavy smokers are less likely than non-smokers to wear a seat belt. - X More info O B. Ho: Heavy smokers are less likely than non-smokers to wear a seat belt. H: Heavy smokers are not less likely than non-smokers to wear a seat belt. Number of Cigarettes Smoked per Day O OC. Ho: The amount H: The amount of smoking is not independent of seat belt use. 15-34 35 and over 36 smoking is independent of seat belt use. 1-14 Wear Seat Belts 183 23 Don't Wear Seat Belts 158 13 46 O D. Ho: The amount of smoking is dependent upon seat belt use. H: The amount of smoking is not dependent upon seat belt use. Determine the test statistic. Print Done - (Round to three decimal places as needed.) Determine the P-value of the test statistic. P-Value = (Round to three decimal places as needed.) 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 are less concerned about their health and safety and are therefore less inclined to we belts, Is this theory supported by the sample data?
