Coefficient Standard Error t Stat 2.972224 P-value 0.005484 Intercept 13.869436 4.6663486 6 3 0.347276 Weight Loss (X) 0.9970326 1.0456704 3.025459 HO: 0 H1: >0 df = 33 Reject HO if t > 1.692 (in appendix B.5) 3.025 > 1.692 We will reject the null hypothesis because 3.025 is greater than 1.692. At .05 level of significance, we can conclude that the regression line is positive.
