Answer: power of the test, which is the probability of correctly rejecting the null hypothesis when it is false.
The **power of a test** is the probability of correctly rejecting a false null hypothesis, which is a key concept in hypothesis testing. It is distinct from the **p-value** (the smallest significance level for rejecting the null) and the **level of significance** (the probability of a Type I error). Understanding these components is essential for interpreting hypothesis test results.
