Let p1 -p2 denote two population proportions, and let p1 .39 and p2 = 49 be the sample proportions of samples of sizes 150 and 200, respectively. Then a large sample confidence interval for p1 - P2 With a confidence level of approximately 99% is determined by Select one: a. - .10 1.96(.071 1) b.-.10 1.65(.050 1) c. - .10 2.58(.0028) d. .10 1.96(.0051) e. - .10 2.58(.0532) +
