Which of the following is correct? A)When sample size increases, both α and β may decrease. B)Type II error can only occur when you reject H₀. C)Type I error can only occur if you fail to reject H₀. D)The level of significance is the probability of Type II error.

Option A is correct as an increase in sample size can lead to a decrease in both type I and type II errors. This is because a larger sample size leads to increased power, which decreases the likelihood of both types of errors. Option B and C are incorrect as type II errors can occur regardless of whether H₀ is rejected or not, and type I errors can occur if H₀ is rejected. Option D is incorrect as the level of significance is the probability of making a type I error, not a type II error.
