WebbThe difference of two proportions follows an approximate normal distribution. Generally, the null hypothesis states that the two proportions are the same. That is, H0: pA = pB. To conduct the test, we use a pooled proportion, pc. The pooled proportion is calculated as follows: p c = x A + x B n A + n B The distribution for the differences is: Webb16 juli 2024 · P values are often interpreted as your risk of rejecting the null hypothesis of your test when the null hypothesis is actually true.

Webbp -value is a probability that a random sample from the distribution that corresponds to null-hypothesis will show the "worst" results than we have seen for tested sample. The worst here means that the observed number of successful trials will be at least as far as 32 from the expected number under null hypothesis.
