Question

In each case, determine whether the sample sizes are large enough to conclude that the sampling distribution of (p̂1 - p̂2) is approximately normal.
a. n1 = 10, n2 = 12, p̂1 = .50, p̂2 = .50
b. n1 = 10, n2 = 12, p̂1 = .10, p̂2 = .08
c. n1 = n2 = 30, p̂1 = .20, p̂2 = .30
d. n1 = 100, n2 = 200, p̂1 = .05, p̂2 = .09
e. n1 = 100, n2 = 200, p̂1 = .95, p̂2 = .91
