QUESTION 15 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. ух ух 1 60 5 85 0 63 4 89 1 65 6 90 2 70 8 90 5 70 4 90 1 70 5 90 4 80 7 94 6 90 9 100 2 80 7 100 3 80 6 100 Fit a linear regression model relating blood pressure rise in millimeters of mercury (y) to sound pressure level in decibels (x) using least squares. Does a simple linear regression model seem reasonable in this situation? What are the least squares estimate of the slope? O No, slope: 0.174 O Yes, slope: 0.174 O Yes, slope: -10.132 O No, slope: -10.132
