Consider the following two models, E(Y) = 0 + 1X1 + 2X2 + 3X1X2 , and E(Y) = 0 + 1X1. The SSE of the two models are 400 and 600, respectively. Using...

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?
