When a test statistic has a continuous distribution, the P-value has a null uniform distribution, P(P-value ) = for 0 < <

When a test statistic has a continuous distribution, the P-value has a null uniform distribution, P(P-value ≤ α) = α for 0 < α < 1. For Fisher’s exact test, explain why under the null, P(P-value ≤ α) ≤ α for 0 < α < 1.
