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

When b₁ is calculated to be +2.0 in a multiple regression problem involving two independent variables, it means that the estimated mean of Y increases by 2 units for each increase of 1 unit of X₁, holding X₂ constant. This means that the effect of X₁ on Y is being measured while controlling for the influence of X₂. The other options are incorrect.
