Which of the following approaches is a good way to proceed with the influence diagram building for a problem?
 a. The influence diagram for the entire problem is build first and then separate portions are clustered to form separate models.
  b. The influence diagram for all the model parts at the same level are built in parallel to reduce the likelihood of error.
  c. The influence diagram is reverse engineered the diagram is developed in the opposite direction starting with the model output.
  d. The influence diagram for a portion of the problem is built first and then expanded until the total problem is conceptually modeled.

Question 2

Platinum Gym has 10,000 gyms members out of which 1500 memberships included Unlimited Fitness Training and use of the tanning salon, and out of which 750 included Unlimited Hydromassage. If the Fitness Training are considered A, the use of the tanning salon are considered B, and the Hydromassage are considered C, then the associate rule for these sales become If A and B are purchased, then C is also purchased. Calculate the confidence level.

Answer to Question 1

d
RATIONALE: The influence diagram for a portion of the problem is build first and then expanded until the total problem is conceptually modeled.

Answer to Question 2

0.5

RATIONALE: Total memberships = 10,000
Packages of A and B = 1,500
Packages of A, B, and C = 750

The association rule If A and B are purchased, then C is also purchased has a support of 750 out of 1500 sales. The confidence level = total support/total memberships which is 750/1,500 = 50
