selected BP as a root node.
A marks: From the decision tree built in A write three classification rules using the
normalized values first then return it to the original values.
A marks: Write an association rule for BP Cholestrol", which rule has the highest
accuracy? Write the corresponding support and accuracy.
A marks: Repeat parts b c and d in A using the Nave Bayes GaussianNB classifier.
A Compare the performance of the Nave Bayes against the built decision tree and random forest
classifiers using confusion matrix. Based on the comparison, which one is the best to use with
the given datat set?
