Close Friends How many close friends do you have? You know, the kind of people you like to talk to about important personal matters. Do men and women tend to differ on the number of close friends? And if so, by how much do men and women differ with regard to how many close friends they have? One of the questions asked of a random sample of adult Americans on the 2004 General Social Survey (GSS) was: From time to time, most people discuss important matters with other people. Looking back over the last six months-who are the people with whom you discussed matters important to you? Just tell me their first names or initials. The interviewer then recorded how many names each person gave, along with keeping track of the person's sex. The GSS is a survey of a representative sample of U.S. adults who are not institutionalized. 1. Identify the variables recorded. Also classify each as either categorical or quantitative, and identify each variable's role: explanatory or response. 2. Did this study make use of random assignment, random sampling, both, or neither? 3. Was this an experiment or an observational study? Explain how you are deciding. 4. In words, state the null and the alternative hypotheses to test whether American men and women differ with regard to how many friends they have. Close Friends How many close friends do you have?
