答案和详解如下：

Q18. If the probability of a Type I error decreases, then the probability of:

A)   incorrectly accepting the null decreases.

B)   a Type II error increases.

C)   incorrectly rejecting the null increases.

Correct answer is B)

If P(Type I error) decreases, then P(Type II error) increases. A null hypothesis is never accepted. We can only fail to reject the null.
