The following two equations were estimated using the data in MEAPSINGLE. The key explanatory variable is lexppp, the log of expenditures per student at the school level. math4 = 24.49 + 9.01 lexppp - .422 free - .752 Imedinc – .274 pctsgle (59.24) (4.04) (.071) (5.358) (.161) n = 229, R2 = .472, R = .462. math4 = 149.38 + 1.93 lexppp – 060 free – 10.78 Imedinc – .397 petsgle + .667 read4 = (41.70) (2.82) (.054) (3.76) (.111) (.042) n = 229, R2 = .749, R = .743. (i) If you are a policy maker trying to estimate the causal effect of per-student spending on math a test performance, explain why the first equation is more relevant than the second. What is the estimated effect of a 10% increase in expenditures per student?
