In a comparative study of two new drugs, A and B, 275 patients were treated with drug A, and 400 patients were treated with drug B. (The two treatment groups were randomly and independently chosen.) It was found that 178 patients were cured using drug A and 300 patients were cured using drug B. Let p, be the proportion of the population of all patients who are cured using drug A, and let p, be the proportion of the population of all patients who are cured using drug B. Find a 95% confidence interval for p,-p. Then find the lower limit and upper limit of the 95% confidence interval. Carry your intermediate computations to at least three decimal places. Round your responses to at least three decimal places. (If necessary, consult a list of formulas.) Lower limit: Upper limit:
