The director of the MBA program at Salterdine University wants to develop a procedure to determine which applicants to admit to the MBA program. The director believes that an applicant's undergraduate grade point average (GPA) and score on the GMAT exam are helpful in predicting which applicants will be good students. To assist in this endeavor, the director asked a committee of faculty members to classify 70 of the recent students in the MBA program into two groups: (1) good students and (2) weak students. The fileMBAStudents.xlsmthat accompanies this book summarizes these ratings, along with the GPA and GMAT scores for the 70 students.

Question: Use XLMiner's standard data partition command to partition the data into a training set (with 60% of the observations) and validation set (with 40% of the observations) using the default seed of 12345. Use discriminant analysis to develop a classifier for this data. How accurate is this procedure on the training and validation data sets? Round your answers to one decimal place.
