B. The failure to correctly reject the null hypothesis is referred to as a Type 1 error (a).

C. The failure to correctly reject the alternative hypothesis is referred to as a Type II error (B).

D. The level of significance is quantitatively defined as a and the statistical power of a test is quantitatively defined as 1 - a.

Explanation / Answer
