Learning Objectives

Describe the rationale behind the sign test
Describe how the t-test can be used to compare a single mean to a hypothesized value
Compare the means for two paired or unpaired groups using a two-sample t-test

We have already encountered a number of cases where we wanted to ask questions about the mean of a sample. In this chapter, we will delve deeper into the various ways that we can compare means.
