Given the simple regression model Y = Bo + ,X and the regression results that follow, test the null hypothesis that the slope coefficient is 0 versus the alternative hypothesis of greater than zero using probability of Type I error equal to 0. 10, and determine the two-sided 95% and 99% confidence intervals. a. A random sample of size n = 37 with by = 6 and sp, = 1.7 b. A random sample of size n = 49 with b, = 6.2 and Sp, = 1.7 C. A random sample of size n = 37 with b, = 3.4 and Sp, = 1.25 d. A random sample of size n = 25 with b, = 9.3 and Sp, = 1.2 a. Test the null hypothesis that the slope coefficient is 0 versus the alternative hypothesis of greater than zero using probability of Type I error equal to 0.10. Reject Ho. There is sufficient evidence that the slope coefficient is greater than zero. Determine the two-sided 95% confidence interval. ( 2.55, 9.45 ) (Round to two decimal places as needed.) Determine the two-sided 99% confidence interval. (Round to two decimal places as needed.)
