QUIZ-4(22 x 0.5 = 10 +1 bonus point). Due Date: July 28, 2015
Instructions:
This quiz has a total of 22 multiple choice questions (MCQ) for half point each including two bonus questions. All questions are compulsory.

b. An imaginary line drawn in such a way that the total variance of distance for each data point from this line is maximized.
c. An imaginary line drawn in such a way that the total variance of distance for each data point from this line remains constant.
