Construction costs in East LA is not cheap. You want to build a simple cost estimator for construction costs, and you hope to find a useful linear relationship between cost (y) and floor space (x). You have data from a sample of four recently completed building projects: A. Since stat is not outside the critical values of ‡4.303, we can't reject the B=0 null hypothesis. B. Since stat is not outside the critical values of +2.182, we can't reject the B=0 null hypothesis C. Since stat is outside the critical values of ‡4.362, we can reject the B=0 null hypothesis. D. Since tstat is outside the critical values of +_3.182, we can reject the B=0 null hypothesis
