Given a dataset in the following table,

(a) Show which decision will be chosen at the root of the decision tree using

information gain, Gini index, and CART measures. Show all split points for all

attributes.

(b) What happens to the purity if we use Instance as another attribute? Do you think

this attribute should be used for a decision in the tree?

Given a dataset in the following table, (a) Show which decision will
