1. Suppose that you have a random sample of couples. You are interested in seeing the typical difference of their heights. You take the heights of each couple and calculate `diff = male_height – female_height` and then find that the typical value of `diff` is 3 inches i.e. typically men are 3 inches taller than average. Does this require a two-sample means test? Explain why or why not.
