What is power? The probability that a test correctly reacts a true nun hypothesis 1- beta beta alpha/2 1-alpha/2

Solution

Solution :

The power of any test of statistical significance is defined as the probability that it will reject a false null hypothesis.

Statistical power is inversely related to beta or the probability of making a Type II error. In short, power = 1 – .

Power = The complement of (i.e. 1 - ), this is the probability of correctly rejecting H₀ when it is false.

Hence the option two is correct. (2) 1 – .
