Q1. Assume that we have selected two independent random samples from populations having proportions p1 and p2 and that 1 = 800/1000 = 0.8 and 2 = 950/1000 = 0.95. Estimate a 95 percent confidence interval for p1 - p2. Interpret this interval. Can we be 95 percent confident that p1 - p2 is less than 0? That is, can we be 95 percent confident that p1 is less than p2?
