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. 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 60 7 100 3 80 6 100 Fit a linear regression model relating blood pressure rise in millimeters of mercury (v) to sound pressure level in decibels (x) using least squares. Does a simple linear regression model (slope) seem reasonable in this situation? Input Yes or No. Blank 1 What are the least squares estimate of the slope? Input answer up to 3 decimal places, i.e., 0.000. Blank 2
