In the summer of 2011, the Chicago libraries recorded the number of participants per branch of the library versus the number of books read from that branch.  They wanted to predict the number of books read at each branch based on the number of participants in the summer program.  The least squares regression equation was  books read = -657.0 +24.74 participants For one branch of the library the number of participants was 1142. The number of books read was 30310.  Find the residual.

A least squares regression equation was computed to predict the weight (lbs) of a 3 year old toddler based on the toddler’s height (in). The equation was yhat =  5.63 + 0.618x.  (The data set included toddlers between roughly 24 and 48 inches.)  Find the predicted weight of a toddler that was 35 inches tall.
