The weight of a car (in pounds) can influence the mileage (in mpg) that the car can obtain. A random sample of 17 cars was taken and the weight and mileage were recorded for each. The data are in the table below. X, weight (in pounds) Y, mileage (in mpg) 4500 17 3000 31.4 2250 38.9 3000 31.5 2500 40.9 3500 28 4000 23.1 3500 28 5500 13.2 3500 31.3 2250 41.1 4500 19.5 2750 36.3 2750 46.9 3500 32.6 3500 28 3000 32.2

c) Find the equation of the best-fitting line (the least squares regression equation). Round values to 3 decimal places. Include the restricted domain. equation: Y *X restricted domain: pounds <= x <= pounds d) Interpret the slope from part c in the context of this problem. (Pay attention to the units) we can on . Every time we increase Select an answer by expect Select an answer v to Select an answer v by average. e) Interpret the Y-intercept from part c in the context of this problem. Include units. we expect • When Select an answer is Select an answer to be

Looking at your answers above, predict the mileage for the one above that it made sense to do so. Make sure you use the stored equation and not the rounded equation from part c. Round final answer to 3 decimal places. The predicted mileage for a randomly selected car that has a weight of pounds is g) Compute the residual for the following ordered pair in the data: (3500, 28). Make sure you use the stored equation and not the rounded equation from part c. Round final answer to 3 decimal places. The residual for the car with a weight of 3500 pounds is Interpret what this value means in the context of this problem. The actual mileage of a randomly selected car with a weight of 3500 pounds is Select an answer what was predicted.
