Suppose you estimate the sample regression function $$tes\widehat { t~ sco}re _ { i } = 61.13 + 9.42 \cdot \text { Age } _ { i } + 2.57 \cdot \text { Green } _ { i } - 6.32 \cdot \text { Brown } _ { i } + 1.48 \cdot \text { Other } _ { i }$$

When age is equal to zero, the only term that remains in the equation is the intercept term of 61.13. Therefore, students with blue eyes would, on average, score 61.13 points. The other variables (Green, Brown, Other) are not relevant when age is zero.
