The probability of type i error is
WebbThe POWER of a hypothesis test is the probability of rejecting the null hypothesis when the null hypothesis is false.This can also be stated as the probability of correctly rejecting the null hypothesis.. POWER = P(Reject Ho Ho is False) = 1 – β = 1 – beta. Power is the test’s ability to correctly reject the null hypothesis. A test with high power has a good chance … WebbHowever, if 100 tests are each conducted at the 5% level and all corresponding null hypotheses are true, the expected number of incorrect rejections (also known as false positives or Type I errors) is 5. If the tests are statistically independent from each other, the probability of at least one incorrect rejection is approximately 99.4%.
