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. Sound pressure 60 65 100 94 90 89 85 80 70 90 level in decibels, x Blood pressure rise 1 1 6 7 5 4 5 3 1 4 in mL of mercury, y Questions: a) Draw a scatter plot of the data using your calculator but do not upload it. Based on the scatterplot, describe the relationship between the two variables in the context of the problem. Use a complete sentence. b) Compute the correlation coefficient r, using the calculator. Round to 3 decimal places. c) Give the equation of the regression line. Round your numbers to 5 decimal places. d) Interpret the slope of the regression line in the context of the problem. e) Find the predicted mean rise in blood pressure level associated with a sound pressure level of 82 decibels. Round to 1 decimal place. Show your work or explain how you obtained your
