Question
A classification tree is built on the data below
to predict whether or not a student will pass a
course. The predictor variables include the
categorisation of 2nd year marks (categorised
as high (H) / medium (M) / or low (L)) and
whether or not the majority of lectures were
attended (yes (Y) or no (N)). The response is
coded as a pass (P) or fail (F).
