The weight of a car (in pounds) can influence the mileage (in mpg) that the car can obtain. A random sample of 18 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) 3500 32.6 4000 23.4 4000 23.6 2250 53.3 2500 40.9 3000 32.2 2250 38.9 4500 17 2750 46.9 3500 3000 31.5 3500 28 4500 17.2 4500 19.5 2250 41.1 4000 23.1 3000 31.4 3000 31.4 28

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: restricted domain: 2250 pounds <= x <= 4500 pounds d) Interpret the slope from part c in the context of this problem. (Pay attention to the units) Every time we increase the weight by 1 Pound we can expect the mileage to decrease by 0 х Mpg on average. e) Interpret the Y-intercept from part c in the context of this problem. Include units. • When weight is

. When weight is Pounds we expect the mileage to be Mpg Does it make sense to interpret the Y-intercept on this problem? Why or why not? Select an answer f) Should you use the regression equation to predict the mileage of a randomly selected car that has a weight of 3637 pounds? Select an answer Should you use the regression equation to predict the mileage of a randomly selected car that has a weight of 6700 pounds? Select an answer 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.

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: (3000, 31.4). 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 3000 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 3000 pounds is Select an answer what was predicted.
