# Thread: reject the null hypothesis?

1. ## reject the null hypothesis?

Am I going crazy or is this a trick question? (homework assignment)

"Why don't we reject the null hypothesis when the test statistic from a sample falls in the non-rejection region?"

I thought we did?

Re-read what you wrote. We don't reject it because it is not in the rejection region. However, if we don't reject it and its false, then we've commited a type I error.
