Question 1050284
Need to Know:
Type I Error involves the <u>rejection of a null hypothesis that is actually true</u>.
There is a value of alpha  probability that we will reject a true null hypothesis. 
 alpha level of confidence = .01 
a. What is the probability that you will make a Type I error 
given that the null hypothesis is true?  .01 
(the confidence level tells one what the probability of making a Type I error is.)
b. What is the probability that you will make a Type I error given that the null
hypothesis is false? 
By Definition: Type I Error did not occur then ... 
P(Type I error given that the null hypothesis is false) = 0
