(B)The maximun probability of comnitting a Type I error is called the power of the test.
(C)  The minimum probability of committing a Type II error is called tbe size of the test.
(D) When the power function is evaluated atμo, the value equais to the probability of committing a Type II error.
(E)None of the above is correct.
