A linear model was fit to predict weekly Sales of frozen pizza (in pounds) from the average Price ($/unit) charged by a sample of stores in a city in 39 weeks over athree-year period. The average Sales were 50,780 pounds(SD=10,051pounds), and the correlation between Price and Sales was 0.635.

If the Price in a particular week was oneSD lower than the mean Price, how much pizza would you predict was sold that week?
