Here is a model of house price as a function of several other variables: =- h 1231\" 1-251! [-1 II! w n'LI arm F! [T ITI m .1.\" COLD\" tml l'll'l :1\" 2m :25\": I- [H m- D'iDml In the model tree, the terminal node, shown as a rectangle, gives information about 11 the number of houses included in that group and y the mean price of the houses in that group. Based on the model tree, answer these questions: 1. What variables are in the model? 2. For houses with a living area less than 103i] square feet, does the number of bathrooms make a difference in price? 3. For houses with a living area between 1030 and 1483 square feet, how much is the typical difference in price between houses with 1 NE baths and houses with 2 bathrooms? 4. Is having a replace associated with a higher house price? What other variables does this depend on
