Develop the indicated confidence interval for the difference between population P-1 P-2 proportions Assume that the samples are independent and that they have been randomly selected.
x1 = 36, n1 = 64 and x2 = 47, n2 = 71; Construct a 95% confidence interval for the difference between population proportions p1 - p2.
a. -0.263 < p1 - p2 < 0.064
b. 0.368 < p1 - p2 < 0.757
c. 0.399 < p1 - p2 < 0.726
d. -0.294 < p1 - p2 < 0.757
