The Cadet is a popular model of sport utility vehicle, known for its relatively high resale value. The bivariate data given below were taken from a sample of fifteen Cadets, each bought "new" two years ago and each sold "used" within the past month. For each Cadet in the sample, we have listed both the mileage, (in thousands of miles), that the Cadet had on its odometer at the time it was sold used, and the price, (in thousands of dollars), at which the Cadet was sold used. These data are shown graphically in the scatter plot (not shown).
The value of the sample correlation coefficient r for these data is approximately -0.890.
