Question

If you create a regression model for predicting the weight of a car (in pounds) from its length (in feet), is the slope most likely to be 3, 30, 300, or 3000? Explain. Choose the correct answer below. A. The only slope that makes sense is 30 pounds per foot, 3 pounds per foot is too small and 300 pounds per foot is too large. B. The only slope that makes sense is 3000 pounds per foot, 300 pounds per foot is too small. C. The only slope that makes sense is 3 pounds per foot, 30 pounds per foot is too large. D. The only slope that makes sense is 300 pounds per foot, 30 pounds per foot is too small and 3000 pounds per foot is too large.

Explanation / Answer

ypical car weight ranges from 3000 - 6000 pounds and an average length of around 7 feet.

So, slope should be around 300 pounds per feet.
