Which of the following statements is most accurate with respect to interpreting a multiple regression with the equation
Yi=b0+b1X1i+b2X2i+b3X3i+εiY_i = b_0 + b_1 X_{1i} + b_2 X_{2i} + b_3 X_{3i} + \varepsilon_iYi=b0+b1X1i+b2X2i+b3X3i+εi_
A
εi\varepsilon_iεi represents the stochastic part of the model_
B
If the change in each of the variables X1X_1X1, X2X_2X2, and X3X_3X3 is zero, the change in YYY is b0b_0b0
C
b3b_3b3 represents the percentage variation in YYY that can be explained by the variable X3X_3X3
