C: What happens when a Type 1 error is made?
D: What happens when a Type 2 error is made?
E: What is the probability of a Type 1 error for samples of size 10, 20, and 30?
F: What is the advantage of of increasing the sample size for control chart purposes? What error probability is reduced as the sample size is increased?
