Consider the following two models, E(Y) = β0 + β1X1 + β2X2 + β3X1X2 , and E(Y) = β0 + β1X1. The SSE of the two models are 400 and 600, respectively. Using α=0.05, and a sample of size 15, in testing whether X2 contributes significantly to the prediction of Y, what is the value of the appropriate critical value?

A. 3.98

B.4.84

C.3.59

D.5.26

E.none of the above
