Suppose we want to estimate the effects of alcohol consumption (alcohol) on college grade point average (cGPA). In addition to collecting information on grade point averages and alcohol usage, we also obtain attendance information (say, percentage of lectures attended, called attend). A standardized test score (say, SAT) and high school GPA (hsGPA) are also available (i) Should we include attend along with alcohol as explanatory variables in a multiple regression model? (Think about how you would interpret beta-alcohol.)
(ii) Should SAT and hsGPA be included as explanatory variables? Explain.
