7.5: Critical values, p-values, and significance level

WebMay 12, 2024 · To do this, we simply split it in half so that an equal proportion of the area under the curve falls in each tail’s rejection region. For α = .05, this means 2.5% of the area is in each tail, which, based on the z-table, corresponds to critical values of z ∗ = ±1.96. This is shown in Figure 7.5. 2.
