The computer output for the multiple regression analysis provided this information for 15 data points.
Model: y=B0 +B1X1+B2X2+B3X3
b0=1.04 b1=1.29 b2=2.72 b3=0.41
SE(b1)=0.42 SE(b2)=0.65 SE(b3)=0.17
a)Which, if any, of the independent variables contribute the information into prediction? Explain.
b)Give the least-squares prediction equation. Provide the assumptions for the error term in your equation.
c)What is practical interpretation of B1? B2? B3?
