In the book Business Research Methods (5th ed.), Donald R. Cooper and C. William Emory discuss studying the relationship between on-the-job accidents and smoking. Cooper and Emory describe the study as follows: Suppose a manager implementing a smoke-free workplace policy is interested in whether smoking affects worker accidents. Since the company has complete reports of on-the-job accidents, she draws a sample of names of workers who were involved in accidents during the last year. A similar sample from among workers who had no reported accidents in the last year is drawn. She interviews members of both groups to determine if they are smokers or not. The sample results are given in the following table. On-the-Job Accident Smoker Yes No Row Total Heavy 15 9 24 Moderate 9 8 17 Nonsmoker l O l 5 2 5 Column total 34 32 66 [ Expected counts are below observed counts Accident No Accident Total Heavy 15 9 24 12.36 11.64 Moderate 9 8 17 8.76 8.24 Nonsmoker 10 15 25 12.88 12.12 (b) For each cell in the above table, find the corresponding cell, row, and column percentages. (Round your answers to 2 decimal places.) X Answer is not complete. Accident No Accident Heavy Cell = 22.72 % Cell = % Row = 13.63 X % Row = % Column 15.15 X % Column = % = Moderate Cell = % Cell = % Row = % Row = % Column % Column = % Nonsmoker Cell = % Cell = % Row = % Row = % Column % Column = % =(c) Use the Minitab output in the above to test the hypothesis that the incidence of onthejob accidents is independent of smoking habits. Set a = .01. HO. The sample results are given in the following table.
