The shape of a sampling distribution of p ^ 1 − p ^ 2 ‍ depends on whether both samples pass the large counts condition. If we expect at least 10 ‍ successes and at least 10 ‍ failures in both samples, then the sampling distribution of p ^ 1 − p ^ 2 ‍ will be approximately normal.

The closer that p is to 0.5, the more symmetric the binomial distribution, and therefore closer to Normal. These two ideas are combined to form the Large counts condition np > 10 and n (1 – p) > 10.
