Question:

Multiple choice: Interpret parameter If ŷ = 2 + 3x₁ + 5x₂ - 8x₃, then controlling for x₂ and x₃, the change in the estimated mean of y when x₁ is increased from 10 to 20
a. Equals 30.
b. Equals 0.3.
c. Cannot be given—depends on specific values of x₂and x₃.
d. Must be the same as when we ignore x₂ and x₃.
