1. Suppose we want to estimate the effects of alcohol consumption on college GPA and collect information on college GPA (colgpa ) and alcohol consumption (alcohol, which is a binary variable that takes value 1 if the student drank alcohol in the past month and 0 otherwise) for five college students on campus. students colgpa alcohol u. (Residual) 2,-alcohol 1 2 3 4 5 2.6 2.3 2.9 3.5 2.4 1 0 0 0 1 v) 6 pts) How much of the variation in colgpa for these five students is explained by alcohol? Be precise. vi) (6 pts) List three other possible determinants of college GPA that might be correlated with alcohol consumption. vii) (4 pts) Does a simple regression of colgpa on alcohol necessarily uncover the ceteris paribus effect of alcohol consumption on college GPA? Explain. 1.
