Multiple choice

Styles 1. Simulation models are: a useful when waiting line models are too complex b. useful for conducting experiments using the real system c. preferred because they find optimal solutions. d. usually inexpensive relative to other approaches. 2 A manager has been given the table shown below and is asked to generate random mumbers. Which of the following statements is TRUE? Range # Customers 00-490 50-19 1 80-99 2. There are no customers in the store 49 percent of the time. b. The probability of having one customer in the store is 0.30. c. The relative frequency of having two customers in the store is 0.80. d. If we randomly choose the numbers 0 through 99 enough times, about 99 percent of the time we will have two customers in the store.
