In a multiple regression problem involving two independent variables X₁ and X₂,what does it mean if b₂ is computed to be -1.5? A)The relationship between X₂ and Y is significant. B)The estimated value of Y decreases by an average of 1.5 units for each unit increase of X₁,holding X₂ constant. C)The estimated value of Y decreases by an average of 1.5 units for each unit increase of X₂,holding X₁ constant. D)The estimated average value of Y is -1.5 units when X₁= X₂ = 0.
