Suppose that a test procedure about the population proportion P is performed,and that the sample proportion
is approximately normally distributed.If the alternative hypothesis is H₁ : P ≠ P₀,then the rejection region for a level α = 0.05 is either Z < -1.96 or Z > 1.96.

Quizplus · Accepted Answer

The rejection region for a two-tailed test with a level of significance α = 0.05 is Z < -1.96 or Z > 1.96. This means that if the calculated Z-score falls outside of this range, the null hypothesis can be rejected in favor of the alternative hypothesis.
