For a given sample size, when we increase the probability of Type I error,the probability of a Type II error

Select one:
a. Remains unchanged
b. Increases
c. Decreases
d. Is impossible to determine without more information

Solution

It

OPTION C: DECREASES. [ANSWER]

******************

As we increase the probability of type I error, the critical region goes farther from the true mean; hence, it becomes less in probability (a type II error).
