Critical value z chart

WebMay 12, 2024 · In hypothesis testing, the value corresponding to a specific rejection region is called the critical value, z c r i t (“ z -crit”) or z ∗ (hence the other name “critical region”). Finding the critical value works exactly the same as finding the z-score corresponding to any area under the curve like we did in Unit 1. WebThose critical values will be the same or smaller than those shown in the table below. Consider an example. The critical z-score values when using a 95 percent confidence level are -1.96 and +1.96 standard deviations. The uncorrected p-value associated with a 95 percent confidence level is 0.05.
