Which of the following is correct?
A)When the sample size increases,β may decrease and power would increase.
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.

As sample size increases, the standard error gets smaller, making it easier to detect a true effect. This, in turn, increases the power of the test. However, as the significance level (α) remains the same, the probability of committing a Type II error (β) decreases.
