You may need to use the appropriate appendix table or technology to answer this question. The following table shows the results of a study on smoking and three illnesses. We are interested in determining if the proportions of smokers in the three categories are different from each other. (Let P2 P2, and Pz, represent the proportions of smokers with emphysema, heart problems, and cancer respectively. Use a 0.05 level of significance.) Emphysema Heart problem Cancer Total Smoker 145 75 105 325 Non-smoker 55 125 495 675 Total 200 200 600 1,000 (a) Provide the null and alternative hypotheses. O Ho: Not all population proportions are equal. Hai Pi = P2 = P3 O HO P1 = P2 = P3 Ha Not all population proportions are equal. O Ho: P1 = P2 = P3 Ha All population proportions are not equal. O Hoi All population proportions are not equal. Hai P1 = P2 = P3 (b) Determine the expected frequencies. Emphysema Heart problem Cancer Total Smoker 325 Non-smoker 675 Total 200 200 600 1,000 (c) Compute the sample proportions. (Round your answers to four decimal places.) - ܕP 22 = (d) Compute the critical values (CV;). (Round your answers to five decimal places.) CV 12 = CV 13 - CV 23 CV 12 (e) Give your conclusions by providing numerical reasoning. (Round your numerical answers to four decimal places.)
