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, p̅₁ = 0.05, and p̅₂ = 0.05
