Suppose you estimate the sample regression function

$tes\widehat { t~ sco}re _ { i }=61.13+9.42 \cdot \text { Age }_{i}+2.57 \cdot \text { Green }_{i}-6.32 \cdot \text { Brown }_{i}+1.48 \cdot \text { Other }_{i}$
You should conclude that,holding age constant,students with brown eyes average
A)6.32 points less than students with blue eyes.
B)6.32 points more than students with blue eyes.
C)6.32 points less than other students.
D)6.32 points more than other students.
