WebFor a two-sided test, we compute 1 - α/2, or 1 - 0.05/2 = 0.975 when α = 0.05. If the absolute value of the test statistic is greater than the critical value (0.975), then we reject the null hypothesis. Due to the symmetry of … WebApr 11, 2024 · p_value > ⍺ (Critical value): Fail to reject the null hypothesis of the statistical test. p_value ≤ ⍺ (Critical value): Reject the null hypothesis of the statistical test. The critical value that most statisticians choose is ⍺ = 0.05. This 0.05 means that, if we run the experiment 100 times, 5% of the times we will be able to reject the ...
