In a regression analysis involving 31 observations, the following estimated regression equation was obtained.
y_hat (y^) = -1.9 + .0254 x 1 + .005 x 2 - .15 x 3 + .31 x 4
For this estimate regression equation the value for SSE is = 112
Suppose variables x 2 and x 4 are dropped from the model and the following estimated regression equation is obtained
y_hat (y^) = -1.9 + + .065 x 2 + .44 x 4
For this estimate regression equation the value for SSE is = 256
Use an F test and (alpha) a = .05 to, determine whether x 2 and x 4 contribute significantly to the model.
What is the value of the F test statistic _____
