Suppose that, alternatively, you found the following plot, where the training curve, denoted by "CV train" on the plot below, is the result of using 5-fold cross-validation on the training data set only (NOTE: despite the possibly confusing label, the "CV train" plot is the average, over the 5 folds on the training data, of the CV test/hold-out error obtained for each degree value), while the test curve, denoted by "test" on the plot below, is the result of evaluating on the test data set the classifier that the regression-learning algorithm outputs for the corresponding polynomial-degree d using all the training data as input. test CV KZ train -0.2. 3 DQuestion 7 Based on this information alone, what is the degree of the polynomial you would choose? (Please enter an integer.) Question 8 If you were asked to provide a rough estimate of the generalization error of the classifiers produced by using the model-selection algorithm you used to choose the final classifier, what would that value be
