survey was taken of randomly selected Americans, age 65 and older, which found that 412 of 1012 men and 530 of 1059 women suffered from some form of arthritis. a) Are the assumptions and conditions necessary for inference satisfied? Explain. b) Create a 95% confidence interval for the difference in the proportions of senior men and women who have this disease. c) Interpret your interval in this context. d) Does this suggest that arthritis is more likely to afflict women than men? Explain. a) Are the assumptions and conditions necessary for inference satisfied? Explain. O A. No, it was not a random sample. O B. No, more than 10% of the population was sampled. O C. No, the groups were not independent. O D. Yes, it was a random sample, less than 10% of the population was sampled, the groups were independent, and there were more than 10 successes and failures in each group. b) Let p, be the sample proportion of senior women suffering from some form of arthritis, and let p, be the sample proportion of senior men suffering from some form of arthritis. Create a 95% confidence interval for the difference in the proportions of senior men and women who have this disease, p1 - P2. The confidence interval is (],) (Round to three decimal places as needed.) c) There is 95% confidence, based on these samples, that the proportion of American women, age 65 and older, who suffer from arthritis is between % and % than the proportion of American men of the same age who suffer from arthritis. (Round to one decimal place as needed.)
