Question: Charles tested whether years of service (years) and gender (gender) explained salaries of professors at major universities. From his sample, he estimated a sample regression equation of:

Predicted Salary = $45,000 + $3,000*Years - $500*Gender - $1,000*(Years*Gender)

Where Gender = 1 for females and 0 for males.

Assume that all coefficients are statistically significant.

Interpret the coefficients for YEARS and YEARS*GENDER. (6 points)
