WebThe formula for the calculation for P-value is: Step 1: Find out the test static Z is. Z = ^p−p0 √p0(1−p0) n Z = p ^ − p 0 p 0 ( 1 − p 0) n. Where, ^p = p ^ = Sample Proportion. P0 = P 0 = assumed population proportion in the null hypothesis. N = sample size. Step 2: Look at the Z-table to find the corresponding level of P from the z ...

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.
