A person is trying to decide which SUV to purchase. You recommended using AHP to help with the decision-making process. After an initial interview you have determined that the four criteria the person will base the decision on are: cost, miles per gallon (MPG), horse power (HP), and manufacturer. The following table presents the 4 criteria along with 4 alternatives. This table is just for reference; you will not need it in this exercise.

	Criteria
Alternatives	Cost	Miles per gallon (MPG)	Horse Power (HP)	Manufacturer
Grand Cherokee	$34,635.00	22	210	Jeep
Explorer	$25,999.00	20	292	Ford
4-runner	$27,635.00	21	260	Toyota
Tucson	$16,995.00	24	173	Hyundai

Upon doing the pairwise comparisons, the person said the following:

• Prefers cost over MPG with a strength of 2.
• Prefers cost over HP with a strength of 7.
• Prefers manufacturer over cost with a strength of 3.
• Prefers MPG over HP with a strength of 2.
• Prefers manufacturer over MPG with a strength of 5.
• Prefers manufacturer over HP with a strength of 7.

1. Using the results from the pairwise comparisons, create the A matrix for the criteria.
2. Calculate A_Norm and w^T.
3. Perform the consistency check on the A matrix. Was the person consistent?
