A survey was taken of randomly selected persons from a large country age 65 and older, which found that 411 of 1019 men and 531 of 1052 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 p₁ - P₂, where p, is the sample proportion of senior women suffering from some form of arthritis and p2 is the sample proportion of senior men. c) Interpret your interval in this context. a) Are the assumptions and conditions necessary for inference satisfied? Explain. OA. No. More than 10% of the population was sampled. OB. No. The groups were not independent. C. 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. OD. No. It was not a random sample. b) The confidence interval is (). (Type integers rdecimals rounded to three decimal places as needed.)
