Select all statements that apply to the Null Hypothesis: a) has associated rejection regions that define limits associated with rejecting the Null at the expense of making a probabilistic error. b) It must be demonstrated not to be true by providing a significantly different sample c) It can be represented by confidence interval around a mean d) It represents the existing, normal situation and is assumed to be true. e) The Null hypothesis is tested via a sample and if the sample is good, then the null is accepted. I know that D is one. But I am having trouble figuring out if the other ones apply to the Null Hypothesis or not. His wording is just so vague.
