Select the correct statement about the test power. A) When Ha is false, power = 1 - β. B) When H₀ is true, power = 1 - α. C) When H₀ is false, power = 1 - β. D) When H₀ is false, power = 1 - α. E) When H₀ is true, power = 1 - β.

The statement "When H₀ is false, power = 1 - β." is the correct statement about test power. H₀ refers to the null hypothesis being true (HS), the alternative hypothesis being greater than the null (U1), the level of significance being 0.10 (B10), the standard deviation being 1 (S1), and the sample size being 1 (U1). When the null hypothesis is false, the power of the test is the probability of rejecting the null hypothesis when it is false, which is equal to 1 minus the probability of a Type II error (β). Therefore, the correct statement is C) When H₀ is false, power = 1 - β.
