Week 7 - Hypothesis Testing
The culmination of all our hard work so far this semester will by the study of hypothesis testing. In this experience we will examine each part of the process both conceptually and as a set of calculations. Thorough understanding of these mechanics will ensure you do not make the common mistakes that plague the uninformed. This important procedure is the industry standard technique for scientifically supporting and refuting claims about population means and proportions. You will find that something similar to these tests is used to determine if drugs are safe, new methods are better, or if people's opinions have changed.
- Know the general process of hypothesis testing using p-values
- Learn how to write hypotheses
- Learn how the decision is used to make a formal conclusion.
- The learner will translate written scenarios into corresponding null and alternative hypotheses using correct notation for mean and proportion tests.
- The learner will translate written scenarios and small data sets into corresponding hypothesis tests and use the complete procedure to test claims.
- The learner will write a conclusion in complete sentences that relates the decision to the original hypotheses and includes the level of significance.

Here I have annotated chapter 9 to indicate parts to skip for now and include examples of hypothesis tests using StatKey. I have edited up through example 18; please ignore the TI-84 examples after that.
