Q: to generate one observation coming from this p.m.f.
Answer:
DISC(0.3, -0.1, 0.4, 0, 0.6, 2, 1, 4)
DISC(F(x1), x1, F(x2), x2, . . .)
Q: Suppose there are 3 people in the line called joe.queue and 5 people in the line
called tom.queue. What is the value of the following Arena expression?
Answer:
(NQ(joe.queue) > NQ(tom.queue)) + (TNOW >= 0 The logical expression
(NQ(joe.queue) > NQ(tom.queue)) is false (because 3 ≤ 5) and therefore 0. The
logical expression (TNOW >= 0) is always true (since time is always at least 0) and
therefore 1. Thus, 0 + 1 = 1
Q: TRUE or FALSE?
Answer:
The Arena Call Center model discussed in class used a nonhomogeneous Poisson
process arrival process (with rates varying throughout the day). TRUE

Q: Regarding Linear Congruential Generators (LCG's), select the statement that is
correct.
Answer:
Both
full periodicity and cycle length properties should be considered when choosing a
good LCG.
Q: We are testing a new medication. Our null hypothesis, H0, is the assumption that
the medication is safe. If we reject this null hypothesis but the medication is
actually safe, what type of error have we committed?
Answer:
Since we have incorrectly rejectedthe null hypothesis of safety, we have committed a
Type I error
Q: TRUE or FALSE?
Answer:
In Arena, it is not possible use a single DECIDE module to randomly route
customers to one of three or more destinations. FALSE

Q: TRUE or FALSE?
Answer:
In Arena, you can use the expression EXPO(3) to generate exponential interarrival
times having a mean of 3. TRUE
Q: TRUE or FALSE?
Answer:
In Arena, an alternative expression to generate exponential interarrival times having
a mean of 3 is -(1/3)*LN(UNIF(0,1)) FALSE. This is the Inverse Transform Method
to generate an observation coming from Exp(λ = 3), which has a mean of 1/3.
Q: TRUE or FALSE?
Answer:
In Arena, it is possible to set the maximum capacity of a queue from within a
QUEUE block found in the Blocks template. TRUE. In fact, it's pretty much the only
way.
