ABSTRACT
In Chapters 2 and 6, we introduced the idea of the hypothesis testing framework. In Chapter 6 we discussed three tools you can use to make an objective decision about whether contamination is present or not: prediction intervals, tolerance intervals, and control charts. In this chapter, we provide a full discussion of the statistical hypothesis testing framework, discuss the relationship between confidence intervals and formal hypothesis tests, and discuss hypothesis tests to make inferences about a single population and compare two or more populations.
