B. You are given the following simple linear regression model Y = βX + ε Where the classical linear regression assumptions are all met. Three estimates can be used to approximate the unknown slope coefficient, ß. Σ(Χ.-Χ.Υ. Σ Xi-X ΔΑΣ ΣΧΥ, B₁ = Σχ? βι I Α β, If the decision criterion is the efficiency of those estimators, indicate which one of th estimators to use (You need to show all workings).
