Probability and Sampling Distributions

In the previous chapter, we introduced some definitions of probability, some basic concepts related to probability, and showed you different ways to count the number of possibilities (e.g., the Fundamental Counting Rule, permutations, and combinations). In this chapter, we are going to begin to apply some of those ideas as we start to build a system that will allow us to test hypotheses about populations using data available from samples from those populations. We will begin with a very simple experiment, tossing a coin four times.
