What happens to the probability of committing a Type I error if the level of significance is changed from $\alpha$ = 0.01 to$\alpha$ = 0.05?
A)The probability of committing a Type I error will decrease.
B)The probability of committing a Type I error will increase.
C)The probability of committing a Type I error will remain the same.
D)The change in probability will depend on your sample size.

Question

Quizplus · Accepted Answer

The probability of committing a Type I error is directly proportional to the level of significance (α) chosen. As α is increased from 0.01 to 0.05, the probability of committing a Type I error also increases. Therefore, the best choice is B. The change in probability will not depend on the sample size in this case.
