Independent random samples were selected from two binomial populations. The size and number of observed successes for each sample are shown in the following table:

Sample 1

Sample 2

n1 = 200

n2 = 200

x1 = 110

x2 = 130

a. Test H0: (p1 - p2) = 0 against Ha: (p1 - p2)<0. Use α = .10.


b. Form a 95% confidence interval for (p1 - p2).


c. What sample sizes would be required if we wish to use a 95% confidence interval of width .01 to estimate (p1 - p2)
