In comparing two proportions, suppose that p1 = p2 = .5 and n1 = n2 = 100.
a. Draw a picture of the appropriate sampling distribution, and show where the value P^1 - P^2 = 0.13 falls on it.
b. Find the value of the standardized statistic corresponding to P^1 - P^2 = 0.13.
c. Draw a picture of the standard normal distribution with the standardized statistic you found in part (b) shown on it. Compare it to your picture in part (a).
