Question 669:
1Answer:
No answer provided yet.In hypothesis testing there are two types of errors, Type I and Type II errors (appropriately named). There are basically 4 things that can happen in a hypothesis test. Two of them are not errors and the other two are errors of the aforementioned types. When you correctly reject the null hypothesis there is no error. When you correctly fail to reject the null hypothesis there also is no error.So, when you incorrectly reject the null hypothesis you make a Type I error. When you fail to reject the null hypothesis when it is false, you make a Type II error. Therefore the correct choice is D.
