An article in the Journal of Sound and Vibration (1991,Vol. 151, 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.
Draw a scatter diagram of y (blood pressure rise in millimeters of mercury) versus x (sound pressure level in decibels).Does a simple linear regression model seem reasonable in this situation?Fit the simple linear regression model using least squares. Find an estimate of \(\sigma^{2}\).Find the predicted mean rise in blood pressure level associated with a sound pressure level of 85 decibels.
