I need help remembering the steps for how to create a confidence interval for the following type of problem, using my TI-84 Plus calculator. Please and thank you. “A survey was taken of randomly selected Americans, age 65 and older, which found that 403 of 1002 men and 550 of 1055 women suffered from some form of arthritis. Let p1 be the sample proportion of senior women suffering from some form of arthritis, and let p2 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.”
