WebDefinition 13. The power function of a hypothesis test with a rejection region R is a function of θ defined by β ( θ) = Pθ ( X ∈ R ). A good test should have a power function close to 0 for all θ ∈ Θ 0 and 1 for all so that both type I and type II errors are low. WebThe probability plot below displays the critical values and the rejection regions for a two-sided z-test with a significance level of 0.05. When the z-score is ≤ -1.96 or ≥ 1.96, it exceeds the cutoff, and your results are statistically significant. One-Sided Tests One-tailed tests have one rejection region and, hence, only one critical value.
