Question

What happens to the probability of making a Type II​ error, beta​,as the level of​ significance, alpha​,​decreases? Why?

Answer 1

Lowering the level of significance, α increases the probability of making a Type II error, β.

Explanation:

Lowering the level of significance, α increases the probability of making a Type II error, β.

This is because the region of acceptance becomes bigger, and it makes it less likely for one to reject a null hypothesis, when it is false, the type II error.
