An article in the Journal of Sound and Vibration (Vol. 151, 1991, pp. 383-394) described a study investigating the relationship between noise exposure and hypertension. The following data are representative of those reported in the article. y Y 1 0 1 2 5 1 4 6 2 3 5 4 6 8 4 5 7 9 7 6 1 1 5 4 6 3 5 5 x 60 63 65 70 70 70 80 90 80 80 85 89 90 90 90 90 94 100 100 100 (a) Test for significance of regression using a = 0.05. What is the P-value for this test? Round to 7 decimal places. (b) Estimate the standard errors of the slope and intercept. Standard error of the slope = i .(Round to four decimal places.) Standard error of the intercept = i (Round to three decimal places.) (c) Test Ho: Bo = 0 versus H: Bo O using a = 0.05. Find the P-value for this test. i (Round to six decimal places.)
