Refer to question 5 and answer the following questions:

a. Use the Mahalanobis distance measure approach to DA to classify each of the current students.

b. Create a confusion matrix that summarizes the accuracy of the distance measure approach on the data for the current students. Overall, how accurate does the distance measure approach to DA appear to be on these data?

c. Classify each of the five new applicants from question 5 using the distance measure approach. Whom do you expect to be good students and whom do you expect to be weak?

d. If the two approaches to DA reach the same conclusion about a given applicant, what effect should this have on the MBA director’s opinion of that applicant? What action might the director take if the two approaches to DA suggest conflicting classifications?
