It can be used when the samples are independent, n1ˆp1 ≥ 10, n1ˆq1 ≥ 10, n2ˆp2 ≥ 10, and n2ˆq2 ≥ 10. The formula for the z-test statistic is: z = (ˆp1 − ˆp2) − (p1 − p2) √(ˆp ⋅ ˆq( 1 n1 + 1 n2))

The Large Sample Condition: The sample size is at least 30. Note: In some textbooks, a “large enough” sample size is defined as at least 40 but the number 30 is more commonly used. When this condition is met, it can be assumed that the sampling distribution of the sample mean is approximately normal.
