In a multiple regression problem involving two independent variables, if b₁is computed to be +2.0, it means that: A) the relationship between X₁and 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 X₁equals zero.
