Exercise 13.19 (Algo) METHODS AND APPLICATIONS 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 effects 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 Smoker Heavy Moderate Nonsmoker Column total Heavy Moderate Nonsmoker Total Chi-50 Yes 14 7 13 34 On-the-Job Accident Expected counts are below observed counts: No Accident 9 11.15 9 Accident 14 11.85 7 8.24 13 13.91 No 9 14 32 Row Total 7.76 14 23 16 27 66 13.09 32 34 1.31, DF 2, P-Value Total 23 16 27 66 0.519 of 1 # Next
