Answer
Brief Explanations:
In hypothesis - testing, a Type II error occurs when the null hypothesis is false but we fail to reject it. A Type I error is rejecting a true null hypothesis. A correct decision is either rejecting a false null or not - rejecting a true null. Type β error is another name for Type II error.
