= + Given the simple regression model Y = Bo + B1X and the regression results that follow, test the null hypothesis that the slope coefficient is o 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= 39 with b1 = 8 and Sb1 = 2.9 b. A random sample of size n = 49 with by = 8.3 and = 2.9 c. A random sample of size n= 39 with by = 5.3 and = 1.52 d. A random sample of size n = 32 with by = 9.5 and = 1.5 Isb1 = I561 Iso1 a. Test the null hypothesis that the slope coefficient is o 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. ( OD) (Round to two decimal places as needed.) Determine the two-sided 99% confidence interval. (OD) (Round to two decimal places as needed.)
b. Test the null hypothesis that the slope coefficient is o versus the alternative hypothesis of greater than zero using probability of Type I error equal to 0.10. Ho. There is evidence that the slope coefficient is greater than zero. Determine the two-sided 95% confidence interval. (OD) (Round to two decimal places as needed.) Determine the two-sided 99% confidence interval. D) (Round to two decimal places as needed.)
c. Test the null hypothesis that the slope coefficient is O versus the alternative hypothesis of greater than zero using probability of Type I error equal to 0.10. Ho. There is evidence that the slope coefficient is greater than zero. Determine the two-sided 95% confidence interval. (OD) (Round to two decimal places as needed.) Determine the two-sided 99% confidence interval. ) (Round to two decimal places as needed.)
d. Test the null hypothesis that the slope coefficient is O versus the alternative hypothesis of greater than zero using probability of Type I error equal to 0.10. Ho. There is evidence that the slope coefficient is greater than zero. Determine the two-sided 95% confidence interval. (OD) (Round to two decimal places as needed.)
