The numbers of successes and the sample sizes for independent simple random samples from two populations are x 1equals32, n 1equals40, x 2equals10, n 2equals20. a. Use the two-proportions plus-four z-interval procedure to find an 95% confidence interval for the difference between the two populations proportions. b. Compare your result with the result of a two-proportion z-interval procedure, if finding such a confidence interval is appropriate.
