Errors in Significance Tests

Type 1 Error
A type 1 error is when we wrongly reject a true H0. The probability of this occurring is equal to α.

Type 2 Error
A type 2 error is when we wrongly accept an H0 when a specific Ha is true. The probability if this occurring is equal to 1 minus the power of the test against that Ha.
