In examining the determinants of income, data were collected regarding the characteristics of 45 adults, and the regression Y = β 0 + β 1 X 1 + β 2 X 2 + β 3 X 3 +ε was used, where Y is the annual income (in thousands of dollars), X 1 is the person's age, X 2 is his/her years of education, and X 3 is a dummy variable = 1 if the adult is female.
If you get = 26.3 + 1.38 x 1 + 2.98 x 2 - 0.76 x 3 + 0.34( x 2 ∙ x 3 ) when you run the regression, how would you interpret the coefficient on his/her years of education?
