Question

For the data set shown below, complete parts (a) through (d) below. (a) Find the estimates of beta 0 and beta 1 (b) Compute the standard error, the point estimate for sigma. (c) Assuming the residuals are normally distributed, determine Sb1. (d) Assuming the residuals are normally distributed, test H0: beta 1 = 0 versus H1: beta 1 not equal to 0 at the alpha = 0.05 level of significance. Use the P-value approach. The P-value for this test is Make a statement regarding the null hypothesis and draw a conclusion for this test. Choose the correct answer below. A. Do not reject H0. There is sufficient evidence at the alpha = 0.05 level of significance to conclude that a linear relation exists between x and y. B. Reject H0. There is not sufficient evidence at the alpha = 0.05 level of significance to conclude that a linear relation exists between x and y. C. Do not reject H0. There is not sufficient evidence at the alpha = 0.05 level of significance to conclude that a linear relation exists between x and y. D. Reject H0. There is sufficient evidence at the alpha = 0.05 level of significance to conclude that a linear relation exists between x and y.
