Independent random samples, each containing 800 observations, were selected from two binomial populations. The samples from populations 1 and 2 produced 320 and 400 successes, respectively.

a. Test H0: (p1 - p2) = 0 against Ha: (p1 - p2) = 0. Use α ≠ .05.

b. Test H0: (p1 - p2) = 0 against Ha: (p1 - p2) = 0. Use α ≠ .01.

c. Test H0: (p1 - p2) = 0 against Ha: (p1 - p2) < 0. Use α = .01.

d. Form a 90% confidence interval for (p1 - p2).
