The probability of type 2 error is

WebbThe probability of getting both the two null hypothesis tests correctly accepted is 0.952 0.95 2; this assumes that the tests are independent. It follows that the probability of getting at least one null hypothesis test incorrectly rejected is 1−0.952 =0.0.0975 1 − 0.95 2 = 0.0.0975. That’s higher than our desired Type I error of 0.05.
