In a multiple regression problem involving two independent variables,if b₁ is computed to be +2.0,it means that:
A)the relationship between X₁ and Y is significant.
B)the estimated value of Y increases by an average of 2 units for each increase of 1 unit of X₁, holding X₂ constant.
C)the estimated value of Y increases by an average of 2 units for each increase of 1 unit of X₁, without regard to X₂.
D)the estimated average value of Y is 2 when X₁ equals zero.
