WebWe will use the sampling distribution of p ^ 1 − p ^ 2 as we did for the confidence interval. For a test for two proportions, we are interested in the difference between two groups. If the difference is zero, then they are not different (i.e., they are equal). Therefore, the null hypothesis will always be: H 0: p 1 − p 2 = 0.

In general, the power of a test increases with the sample size. More power means fewer Type II errors (fewer "false negatives").
