(A) Interpret every structural parameter in the following regression:

PROFSALi = 17.969 + 1.3707 EXPi + 3.3336 DUMi + ei where PROFSAL is the professor’s salary;
EXP is the professor’s experience in years;
DUM = 1 if the professor is male; 0 otherwise.
(B) Draw a diagram reflecting the regression results with PROFSAL on the vertical axis and EXP on the horizontal axis.
(C) A male professor with 10 years of experience is expected to make how much in salary?
(D) A nonmale professor with 10 years’ experience is expected to make how much in salary?

(E) What would be the new values of the structural parameters if the dummy was defined as 1 if the professor is nonmale; 0 otherwise?
(F) Using the redefined dummy variable regression, how much would a male professor with 10 years of experience make in salary?
