what is the probability of a type II error when α=0.05 ?
Correct answer: D. Cannot be determined without more information
- A. 0.025
- B. 0.95
- C. 0.05
- D. Cannot be determined without more information
Explanation
Alpha is the Type I error probability, whereas beta is the Type II error probability and depends on the alternative value, sample size, variability, and test design. Therefore, alpha = 0.05 alone cannot determine beta.
