A regression analysis involving 45 observations relating a dependent variable and two independent variables resulted in the following information.
ý = 0.406 + 1.3385X, + 2X2
The SSE for the above model is 43. When two other independent variables were added to the model, the following information was provided.
ý = 1.9 – 3X + 12X2 + 4Xg + 8x,
This model's SSE is 36.
At a 0.05 level of significance, test to determine if the two added independent variables contribute significantly to the model.
State the relevant null and alternative hypotheses.
O Ho: One or more of the parameters is not equal to zero.
H₂: B₁ = B₂= B3 =B4 = 0
O Ho: One or more of the parameters is not equal to zero.
H₂: B3 =B4 = 0
O Ho: B3 = P4 = 0
H₂: None of the parameters are equal to zero.
ⒸH₁: B3 =B₁ = 0
H: One or more of the parameters is not equal to zero.
O Ho: B₁ = P₂ = B3 =B4 = 0
H: One or more of the parameters is not equal to zero.
