TRUE or FALSE? An Arena ASSIGN module can be used to assign values to attributes but not variables. - ANSWER-FALSE. It can be used for both
Suppose X is a discrete random variable that can take on four possible values: −2, 1, 4, and 7. The associated probabilities are, respectively: 0.1, 0.3, 0.2, and 0.4. Find an expression in Arena to generate one observation coming from this p.m.f. - ANSWER-DISC(−2, 0.1, 1, 0.4, 4,
0.6, 7, 1)
Suppose there are 3 people in the line called joe.queue and 2 people in the line called tom.queue. What is the value of the following Arena expression? NQ(tom.queue) ∗ NQ(joe.queue) + (TNOW < −1) - ANSWER-The logical expression (TNOW < -1) is false (since time is always at least 0). Thus, NQ(tom.queue) ∗ NQ(joe.queue) − (TNOW <
−1) = 6 + 0 = 6.

TRUE or FALSE? The Arena Call Center model discussed in class restricted all servers to one specialty product each. - ANSWER-FALSE.The use of resource sets allowed certain servers to work on multiple products.
The runs "up and down" test is most often used to test for goodness-of- fit of observations. - ANSWER-FALSE. It's a test for independence.
Draw an Arena DECIDE block - ANSWER-It's a sideways diamond.
In what Arena template would you find the Sequence spreadsheet? - ANSWER-Advanced Transfer.
In Arena, you can LEAVE a station. What is the analogous block to use to get into a station? - ANSWER-ENTER
Which method is not a viable way for an entity to LEAVE a resource? (i) Route; (ii) Connect; (iii) Move; (iv) Transport; (v) Convey. (There may be more than one correct answer.) - ANSWER-Move
TRUE or FALSE? Suppose that U1, U2, . . . are truly i.i.d. U(0,1) random variables. Then a 95% chi-square goodness-of-fit test for uniformity will incorrectly reject uniformity of the observations about 5% of the time. - ANSWER-TRUE. (That's what Type I error is.)
