You are considering six independent variables for inclusion in a regression model. You select a sample of n = 40, with the following results:
k = 2 T = 6 + 1 = 7 R2k = 0.214 R2T = 0.653
a. Compute the Cp value for this two-independent-variable model.
b. Based on your answer to (a), does this model meet the criterion for further consideration as the best model? Explain.
