How do I start this...

An owner of a large car lotbelieves 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 from0to60miles 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 bemuch less demand if gas prices rise as predicted. The owner gathers data on20vehicles. The data is provided below. Use Excel to calculate the correlation coefficientrbetween the two data sets. Round your answer to two decimal places.
