Question

I estimate a multiple regression based on the following variables. The dependent variable is student test scores. The independent variables are mother’s education and father’s education, each measured in years, and the sex of the child, coded 0 if male and 1 if female. I obtain the following regression results:

-----------------------------------------------

     Scores          |      Coef.   Std. Err.          

--------------------+--------------------------

       mom_ed    |         4.000   1.0000         

        dad_ed      |         2.000 .02500            

       sex              |         -5.000 1.0000       

       _cons          |       20.000 2.000

What is the predicted test score for a female student whose parents have no formal education?

Explanation / Answer

We need to find the predicted test score when:

mom_ed = 0

dad_ed = 0

sex = 1 [For female]

Hence,

Predicted test score = 0(4) + 0(2) + 1(-5) + 20 = 15

Option C is correct.
