Consider the following data set

$($i$)$ Considering $$Decision$$ as the target variable, which of the attributes would you select as the root in a decision

tree with multi$-$way splits using the information gain impurity measure?

$($ii$)$ For the same data set, suppose we decide to construct a decision tree using the Gini index impurity measure,

which attribute would be the best option to use as the root node?

$($iii$)$ Use the Gini index impurity measure for multi$-$way split and construct the full decision tree for the given

data set.
