1. (16pts) In each situation, indicate whether you think an observational study or a randomized exper- iment would be used. Also specify the explanatory variable (exposure/treatment) and the response (outcome) variable. (a) A teacher wants to compare the grade point averages of female students who are in sororities to the grade point averages of female students who are not in sororities. (b) A doctor wants to compare the effectiveness of two allergy medications. (c) A social psychologist wants to determine whether restaurant servers will get better tips if they introduce themselves by name to the people they serve. (d) A child psychologist wants to find out whether there is an association between the amount of television 6-year-old children watch and how often they bully other children in school.
