An owner of a large car lot believes that fuel prices are going to rise significantly and wonders how this rise might affect demand for the high-performance vehicles. Specifically, the owner is investigating a link between how fast a car can go from
0 to
60 miles per hour (measured in seconds) and the car's economy as measured in miles traveled per gallon used (mpg). If fast cars, which are normally high in demand, are associated with higher mpg then there will be much less demand if gas prices rise as predicted. The owner gathers data on
20 vehicles. The data is provided below. Use Rguroo to calculate the correlation coefficient
r between the two variables. Round your answer to two decimal places.

"mpg" 0 to 60 time (seconds) 28 7.7 25 8.2 25 8.6 22 7.4 22 8 21 6.9 21 7.5 21 7.4 21 7.8 21 8.8 20 6.1 20 6.9 20 7.2 20 7.5 20 7.5 20 7.5 20 7.7 19 6.7 19 7.9 19 8.5
