E. The significance level, denoted by a, is the probability of making a Type I error, that is, the probability of rejecting the null hypotheses when it is actually true.
F. The Type II error is also known as the Consumer's risk because it is the probability that the null hypotheses is not rejected when it is false
H. The level of significance in a test of hypothesis is the probability of making a____________. It is the area under the probability distribution curve where we _______HO
