lf alpha is changed from 0.05 to 0.01, _________.
A) the probability of a Type II error decreases
B) the probability of a Type I error increases
C) the error probabilities stay the same the probability we will retain a false H 0 increases
D) the probability we will retain a false H 0 increases

When alpha is decreased from 0.05 to 0.01, we are increasing the threshold for rejecting the null hypothesis. This makes it less likely for us to reject the null hypothesis when it is actually true, thus increasing the probability that we will retain a false null hypothesis (Type II error).
