In general, increasing sample size (n) effects type I error (alpha) and type II error (beda) in which of the following ways

Question

A. Alpha increases , beta decreases 

B. Alpha increases , beta increases 

C. Alpha decreases , beta decreases 

D. Alpha decreases , beta increases 

Answer 1

Since increasing N, increases the z score, that decreases the area in the tails (alpha) and since beta and alpha are inversely related, it increases beta. So your answer is D. You can use this same logic for your previous question.
