    Quick hypothesis testing question

    What's the probability of not rejecting H_0 given 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

    \mbox{P(reject H_0 | H_0 \;is \;true)} = \mbox{type I error} = \alpha

    \mbox{P(do not reject H_0|H_0 \;is \;true)} = 1-\alpha
