1. Textbook, page 387, 8.7

(a) How would you modify the basic decision tree algorithm to take into consideration the count

of each generalized data tuple (i.e., of each row entry)?

(b) Use your algorithm to construct a decision tree from the given data.

(c) Given a data tuple having the values “systems”, “26. . . 30”, and “46–50K” for the attributes

department, age, and salary, respectively, what would decision tree classification of the status

for the tuple be?

(d) Construct the Na¨?ve Bayesian Classifier and redo part c).

2. Suppose you are given the following data set, in which attribute A through attribute C predict

Class attribute.
