We can connect it to type two errors. For example, you could say this is equal to one minus the probability of not rejecting, one minus the probability of not rejecting, not rejecting the null hypothesis given that the null hypothesis is false. And this thing that I just described, not rejecting the null hypothesis given that the null hypothesis is false, this is, that's the definition of a type, type two error. So you could view it as just the probability of not making a type two error or one minus the probability of making a type two error. Hopefully that's not confusing. So let me just write it the other way. So you could say it's the probability of not making, not making a type, type two error.
