You are hired as a statistical consultant.
Twelve stores in the Fort Collins, CO area have asked you to develop a prediction model for their annual gross sales (sales; measured in $1000 of dollars).

by knowing how much they spend annually on advertising

and the quality of their store’s typical product
(quality; measure on a scale from 0 = very poor quality to 25 = exceptional quality).
