Question: Suppose the regression in Equation (8.30) is estimated using LoSTR and (L o E L) in place of HiSTR and HiEL, where LoSTR (=1-H i

Suppose the regression in Equation (8.30) is estimated using LoSTR and $L o E L$ in place of HiSTR and HiEL, where LoSTR $=1-H i S T R$ is an indicator for a low-class-size district and $L o E L=1-H i E L$ is an indicator for a district with a low percentage of English learners. What are the values of the estimated regression coefficients?

Equation (8.30)

TestScore = 664.1 (1.4) R = 0.290. - 1.9 HiSTR - (1.9) 18.2 HIEL (2.3) 3.5(HiSTR X HIEL), (3.1)
