Problem 2 BSC
Best Multiple Regression EquationFor the regression equation given in Exercise,the P-value is 0.000 and the adjustedR2value is 0.925. If we were to include an additional predictor variable of neck size (in.), the T-value becomes 0.000 and the adjustedR2becomes 0.933. Given that the adjustedR2value of 0.933 is larger, is it better to use the regression equation with the three predictor variables of length, chest size, and neck size? Explain.
Exercise
TerminologyUsing the lengths (in.), chest sizes (in.), and weights (lb) of bears from Data Set 7 in Appendix B, we get this regression equation: Weight = −274 + 0.426 Length + 12.1 Chest Size. Identify the response and predictor variables.
