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: Relationship between floor space and construction costs Floor Space (000s of sq. ft.), x Construction Cost ($000s), y 20 48 35 64 25 80 40 96 Answer choices A. Since tstat is not outside the critical values of ±2.182, we can't reject the β=0 null hypothesis B. Since tstat is not outside the critical values of ±4.303, we can't reject the β=0 null hypothesis. C. Since tstat is outside the critical values of ±4.362, we can reject the β=0 null hypothesis. D. Since tstat is outside the critical values of ±3.182, we can reject the β=0 null hypothesis
