Question

Suppose this model turns out to be our best model when working with apartments: Least Squares Linear Regression of Price Predictor Variables Coefficient Std Error T P VIF Constant 1123.55 1404.09 0.80 0.4277 0.0 Size X1sq 7.678E-04 1.082E-03 1.71 0.0416 68.8 Location-232.236 101.717 -2.28 0.0271 1.1 0.51803 2.45842 -0.21 0.8348 68.6 In determining this was the best model, was it necessary to test the size variable using a t-test? O Yes. The size variable should have been tested using an upper-tailed test. O Maybe. It depends on what happens when we tested the Location variable O Yes. The size variable should have been tested using a two-tailed test. O No. Since the quadratic was found useful, we don't have to test the size variable.

Explanation / Answer

Option C is Correct.

Yes, the size variable should have been tested using a two tailed test because the P value of size variable is very large.
