WebThe conditions for the two-proportion z-test are the same as for the two-proportion z-interval. We are testing the hypothesis H 0: p 1 –p 2 = 0, or, equivalently, H 0: p 1 = p 2. The alternative hypothesis is either; H a: p 1≠p 2, H a: p 1 WebAug 3, 2024 · In order for the results of parametric tests to be valid, the following four assumptions should be met: 1. Normality – Data in each group should be normally distributed. 2. Equal Variance – Data in each group should have approximately equal variance. 3. Independence – Data in each group should be randomly and independently …
