Generalization. Now, let’s step back a bit and think about the scope of our inference. Was this a random sample? Does this study represent all people? How about all men? Is there any population to which we can generalize our conclusion?

In Chapter 5, we will learn how to use the 3S strategy to help us investigate how much evidence the sample data provide to support our conjecture that the long-run probability of men who call is greater for those on the suspension bridge than for those on the wooden bridge. As a result of the simulation analysis method used in Chapter 5 we received a p-value of 0.023.
