Question: Suppose you are interested in estimating the effect of hours spent per week studying (study) on university grade point average ( gpa ) for first-year university students. d. What would a controlled experiment entail in this context? Does such an experiment seem feasible? Consider the more realistic case where students choose how much time to study per week, and you can only randomly sample the pairs study and gpa (at the end of the first year) from the population. Write the population model as gpa = fo + By study +u, List at least two factors contained in u. Are these likely to have positive or negative correlation with study? Thus, comment on the unbiasedness of fi;, which is the OLS estimator of f; calculated from a random sample data.
