Part 2 

Ezekiel 34:18 (ESV) Is it not enough for you to feed on the good pasture, that you must tread down with your feet the rest of our pasture; and to drink of clear water, that you must muddy the rest of the water with your feet?

Elaborate on the above topic with few major points

Need part 1 and part 2 answered with two each references and part 1 (250-300 words) and part 2 (100 words)

Compute xmin, the column vector with the smallest norm, and xmax, the column vector with the largest norm. (Ties are broken arbitrarily.) If applied to the matrix X above the result should be: xmin = ? 1 0 ? , xmax = ? 2 3 ? . You may assume that a function “norm(x)” exists such that norm(xi) is the norm of xi

2. Rank the criteria, compute the rank-sum weights, and determine the score for each alternative. Do the same using the rank reciprocal weights.
3. What are some of the advantages and disadvantages of this method of product selection?.

Activity II: Using MAUT and the AHP, perform an analysis to select a graduate program. Explain your assumptions and indicate which technique you believe is most appropriate for this application.
