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). They would like to know if it is possible to predict the amount of their sales by knowing how much they spend annually on advertising (advert; measured in $1000 of dollars) and the quality of their store’s typical product (quality; measure on a scale from 0 = very poor quality to 25 = exceptional quality).
