Question

Given the simple regression model $Y = \beta_0 + \beta_1 X$ 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 90% and 95% confidence intervals. a. A random sample of size $n = 38$ with $b_1 = 4$ and $s_{b_1} = 2.8$ b. A random sample of size $n = 50$ with $b_1 = 4.1$ and $s_{b_1} = 2.8$ c. A random sample of size $n = 38$ with $b_1 = 2.4$ and $s_{b_1} = 0.99$ d. A random sample of size $n = 26$ with $b_1 = 7.1$ and $s_{b_1} = 0.9$ 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 $H_0$. There is sufficient evidence that the slope coefficient is greater than zero. Determine the two-sided 90% confidence interval. (Round to two decimal places as needed.)
