Question:

In each of the following cases, determine if the sample sizes are large enough so that the sampling distribution of the differences in the sample proportions can be approximated with a normal distribution:
a. n1 = 15, n2 = 20, x1 = 6, and x2 = 16
b. n1 = 10, n2 = 30, p1 = 0.6, and x2 = 19
c. n1 = 25, n2 = 16, x1 = 6, and p2 = 0.40
d. n1 = 100, n2 = 75, 1 = 0.05, and 2 = 0.05
