Hypothesis Testing Testing Outlandish Claims

Learning Objectives Be able to state the null and alternative hypotheses for both one-tailed and two-tailed tests Differentiate between a significance level and a probability level State the five steps involved in hypothesis testing

Big Idea to Remember Don’t mess this idea up!!!!!!!! We Reject We Fail to Reject We never Accept anything.
