Please help with this regression tree question

A ve-node regression tree model is tted to predict the variable miles per gallon (mpg) using two predictors year and acceleration for a subset of the Auto Data. You are given the following results from R: > Auto.tree.2var Auto.tree.2var Auto.tree.2var node), Split, n, deviance, yval * denotes terminal node 1) root 98 5170.00 24.23 2) year 14.1 52 1352.00 23.44 10) acceleration 17.3 5 153.40 30.36 * 11) acceleration > 19.25 6 54.81 17.98 * 3) year > 79.5 26 771.80 31.45 * (a) Sketch the partition of the two-predictor space (see below) with the predicted values of mpg and boundaries in each region. acceleration year (b) What is the predicted miles per gallon of a car with year : 77 and acceleration : 12
