The accuracy of the training set has decreased to 58.4% while the testing set has increased to 59.7%. This tree has a smaller variance between the training and the testing set accuracy rate. Additionally, it is favorable to have a higher accuracy rate on the testing set than the training set. Problem 3 (5 points): Given the decision tree in Figure 1, show how the new examples in Table 1 would be classified by filling in the last column in the table.
