1. Consider the following model: math10 = Bo + Biln(expend) + B2In(enroll) + Bypo a. Using the Michigan Educational Assessment Program data from 1993 (MEAP93), how could you evaluate this model? What available data could be used to capture the student poverty-rate? Explain. Why is it a sensible proxy? b. Evaluate the model and discuss/compare the results both without and then with your proxy for poverty- rate (particularly why (assuming this is the case) do the estimates on expenditure and enrollments decline with the inclusion of a measure of student poverty rate? Which relationships are statistically significant and how do you interpret them? c. Did the R- (and/or adjusted) change much across the two specifications? What does that suggest? 2. [+10 extra credit] Do the same analysis for 7th- grade math scores using the MATHPNL data. In addition to answer A-C parts, answer an additional part "d" comparing the estimates obtained for 7th and 10th grade outcomes. What stands out? What do you
