What's the probability of not rejecting $\displaystyle H_0$ given $\displaystyle H_0$ is true? Is it 1- alpha or 1-beta? I wrote 1-beta on my exam and now I'm pretty sure that it's 1-alpha

$\displaystyle \mbox{P(reject H_0 | H_0 \;is \;true)} = \mbox{type I error} = \alpha$ $\displaystyle \mbox{P(do not reject H_0|H_0 \;is \;true)} = 1-\alpha$

Darn, that's what I thought. I have Bo idea my I put the other answer down. Thanks
