please help

1. Consider the following model: math 10=0+1ln( expend )+2ln( enroll )+3 poverty_r rt+u. 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 R2 (and/or adjusted) change much across the two specifications? What does that suggest? 2. [+10 extra credit] Do the same analysis for 7 th-grade math scores using the MATHPNL data. In addition to answer A-C parts, answer an additional part " d " comparing the estimates obtained for 7 th and 10th grade outcomes. What stands out? What do you learn from the comparison? 1.
