The weight of a car can influence the mileage that the car can obtain. A random sample of 19 cars was taken and the weight (in pounds) and mileage in mpg) were recorded and are in the table below. Test at the sx level for a negative correlation between weight and mileage of cars. weight mileage 3500 28 3000 12.2 4000 23.6 3500 31.3 5500 13.2 4500 17 3000 31.5 3500 31.3 3500 28 2500 40.9 3000 31.4 3000 31.4 3000 322 2750 36.3 2250 533 2750 469 4500 19.5 3500 32.6 4500 17.2 Assume the scatterpice is linear enough to continue N Name the test The conditions are met to use a new Hagement T: Test Statistic • The symbol and value of the random variable on this problem are as follows • Round your answers to decimal places if needed. 0.9232 .
