Confusion Matrix $($Accuracy $0\mathrm{.}7745)$Q$9-4.$ What can you say about the predictive performance of the model?

In $[]$: the data is still overfilling, but the numbers did become smaller. However this model does generalize better than tne tu$11$ class

Q$9-5.$ Express the resulting small tree as a set of rules for the bottom right$-$most leaf $($terminal$)$ node.

In $[]$: $$

Q$9-6.$ Compute the GINI impurity index for the same leaf node. Show the steps of your calculations.

In $[]$: $$

Q$10-1.$ Using the same training dataset, fit a classification tree using a tree with a maximum depth $=3$ and criterion $=$ 'gini'. Visualize the output tree using export$\_$graphviz $.$

Plz help me answer Q$9-5$ and Q$9-6$
