Santa Claus wants to estimate how many ounces of milk will be left at houses he visits based on (1) the assessed property value of the residence; (2) if the children of the household were naughty, nice, or some of each (mixed). Below are some data he took last year. Use the model to predict the amount of milk left for Santa at a $500,000 home of a child who was partly naughty, and partly nice (mixed).
