Suppose the regression in Equation (8.30) is estimated using LoSTR and (L o E L) in place

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 $=1-H i S T R$ 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?
