Question: Education reform is one of the most hotly debated subjects on both state and national policy makers' list of socioeconomic topics. Consider a regression model that relates school expenditures and family background to student performance in Massachusetts using 224 school districts. The response variable is the mean score on the MCAS (Massachusetts Comprehensive Assessment System) exam given in May 1998 to 10th-graders. Four explanatory variables are used:
(1) STR is the student-to-teacher ratio,
(2) TSAL is the average teacher's salary,
(3) INC is the median household income, and
(4) SGL is the percentage of single family households. A portion of the data is shown below; the complete data set can be found on the text website, labeled MCAS.
a. For each explanatory variable, discuss whether it is likely to have a positive or negative causal effect on Score.
b. Estimate the sample regression equation. Are the signs on the coefficients as expected?
c. What is the predicted score if STR = 18, TSAL = 50, INC = 60, SGL = 5?
d. What is the predicted score if everything else is the same as above except INC = 80?
