O CONFIDENCE INTERVALS AND HYPOTHEWS TESTING Confidence interval for the difference of population proportions In a comparative study of two new drugs, A and B, 350 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 234 patients were cured using drug A and 276 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 p₁-P. Then complete the table below. 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) What is the Irwer limit of the 95% confidemos interval 미 what is the upper limit of the 95% confidence interval 0
