5. A group of researchers surveys a large random sample of college students. Students are asked, among other things, whether or not they have a full- or part-time job and whether or not they use Facebook. If the researchers believe that whether or not a college student has a full- or part-time job influences whether or not the student uses Facebook, then A. whether or not a college student has a full- or part-time job would be a response variable. B. whether or not a college student uses Facebook would be an explanatory variable. C. whether or not a college student has a full- or part-time job would be a lurking variable. D. whether or not a college student uses Facebook be a response variable. E. whether or not a college student has a full- or part-time job would be a dependent variable
