How to solve the critical value

WebTo determine critical values, you need to know the distribution of your test statistic under the assumption that the null hypothesis holds. Critical values are then the points on the distribution which have the same probability as your test statistic, equal to the … WebStep 1 Subtract the alpha value from 1. The alpha value is expressed as decimal less than one. As an example, say the alpha value is .03: Video of the Day 1 - 0.03 =0.97 Step 2 Divide the result from above by 2. All two-tailed tests must have this step. The result is 0.97/2 or 0.485 We Recommend Personal Finance
