Use the data in SDATA.XLS and statistical software to run the following regression:

where GPA = grade point average ST = study time per day SAT = SAT score MALE = 1 if the student is male; 0 otherwise (A) Interpret the coefficient on SAT.
(B) Interpret the coefficient on the dummy variable.
(C) Would a male or a nonmale student with the same SAT scores and study time be expected to have a higher GPA? By exactly how much?
(D) What would be the values of the four structural coefficients if the dummy variable had been defined as 1 = nonmale; 0 otherwise?
