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.
