For the data set shown below, complete parts (a) through (d) below. x 3 vl 3 6 7 13 14 4 5 7 80 (a) Find the estimates of Bo and B4. Bo x bo = - 3.58 (Round to three decimal places as needed.) B1 x b, = 2.256 (Round to three decimal places as needed.) (b) Compute the standard error, the point estimate for o. Se = 0.7471 (Round to four decimal places as needed.) (c) Assuming the residuals are normally distributed, determine s,, . = 0.180 (Round to three decimal places as needed.) (d) Assuming the residuals are normally distributed, test Ho: B, = 0 versus H,: B, #0 at the a = 0.05 level of significance. Use the P-value approach. The P-value for this test is. (Round to three decimal places as needed.)
