Suppose the sales (1000s of $) of a fast food restaurant are a linear function of the number of competing outlets within a 5 mile radius and the population (1000s of people) within a 1 mile radius. The regression equation quantifying this relation is (sales) = 1.436*(competitors) + 6.571*(population) + 13.103. Suppose the sales (in 1000s of $) to be of a store that has 3 competitors and a population of 9 thousand people within a 1 mile radius are 51.042 (1000s $). What is the residual?
