Suppose this model turns out to be our best model when working with apartments: Least Squares Linear Regression of Prioe Predictor Variables Coefficient Std Error T P VIF Constant 1123.55 1404.09 0.30 0.4217 0.0 Size -0.51303 2.45342 -0.21 0.3343 63.6 Xlsq 11523504 1.032 E-03 1.?1 0.0416 63.3 Location 432.236 101.2417r -2.23 0.0211 1.1 In determining this was the best model, was it necessary to test the size variable using a t-test? D 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. 0 No. Since the quadratic was found usefulr we don't have to test the size variable
