Question

12. From the regression analysis, suppose that the standard error for the coefficient on X is.021. What is then the test statistic for the null hypothesis that the coefficient is equal to zero? a. 1.667 b. 6.667 c. 0.7214 d. 2.145 e. None of the above 13. From the regression analysis, what is the critical value for the test of the null hypothesis that the coefficient on X is equal to zero at =.05? a. 1.667 b. 2.131 c. 2.145 d. 1.960 e. None of the above 14. In the regression analysis, the value of R suggests that: a. b. C. d. e. Roughly 72% of the variation in Y is explained by variation in x. Roughly 72% of the variation in Y is unexplained by variation in X. Roughly 72% of the variation in X is explained by variation in Y. The correlation coefficient between X and Y is about .72 None of the above. nt hrue a more favorable opinion of Hunter than
