WebJan 6, 2016 · The z table gives detailed correspondences of P (Z>z) for values of z from 0 to 3, by .01 (0.00, 0.01, 0.02, 0.03,…2.99. 3.00). So, if we want to know the probability that Z is greater than 2.00, for example, we find the intersection of 2.0 on the left column, and .00 on the top row, and see that P (Z<2.00) = 0.0228. 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.
