While attempting to measure its risk exposure for the upcoming year, an insurance company notices a trend between the age of a customer and the number of claims
per year. It appears that the number of claims keep going up as customers age. After
performing a regression, they find that the relationship is (claims per year) = 0.17*
(age) +2.04. If a customer is 47 years old and they make an average of 14.72 claims
per year, what is the residual?
