___________ is a measure of dependence between two random variables.
 a. Approximation
  b. Verification
  c. Correlation
  d. Validation

Question 2

Which of the following is a disadvantage of using simulation?
 a. Experimenting directly with a simulation model is often not feasible.
  b. Each simulation run provides only a sample of how the real system will operate.
  c. The simulation models are used to describe systems without requiring the assumptions that are required by mathematical models.
  d. Simulation models warn against poor decision strategies by projecting disastrous outcomes such as system failures, large financial losses, and so on.

Answer to Question 1

c
RATIONALE: Correlation is a measure of dependence between two random variables.

Answer to Question 2

b
RATIONALE: Simulation is not without disadvantages. Each simulation run provides only a sample of how the real system will operate. As such, the summary of the simulation data provides only estimates or approximations about the real system.
