Hypothesis Testing for Population Proportions Hypothesis Testing for Population Proportions Steps in Conducting a Hypothesis Test Hypothesis Test for a Single Population Proportion Hypothesis Test for Difference in Two Population Proportions Calculate the p-value If np0 ≥ 10 and n(1–p0 ) ≥ 10, then the p-value can be computed as the area in the tail(s) of a standard normal beyond z. A small p-value suggests that a surprising outcome has occurred and discredits the null hypothesis.
