In Exercise 13.1 we had paired data because we had a response from both the husband and the wife within a married couple. Suppose that instead of using married couples we just took a large group of people and asked them to what extent they endorsed the statement “Sex is fun for me and my partner” on a four-point scale ranging from “never or occasionally” to “almost always.” We then sorted the data on the basis of the gender of the respondent. We could conceivably get the data we had in Exercise 13.1, though without the pairing. Analyze the data in Exercise 13.1 as if they had been collected from independent groups. What would you conclude?
