Problem 3 Consider the following multiple regression model Y = Bo + B₁X₁i + B2X2i+B3X3i + Ui You want to consider certain hypotheses involving more than one parameter, and you know that the regression error is homoskedastic. You decide to test the joint hypotheses using the homoskedasticity-only F-statistics. For each of the cases below specify a restricted model and indicate how you would compute the F-statistic to test for the validity of the restrictions at the 1% level. 1. B₁-B2; B3 = 0 = 2.
