Q1.
A linear congruential generator (LCG) has parameters (a=5, c=1, m=16). Using a seed of 1,
what is the period of the sequence produced?
A. 4 B. 8
C. 16 D. 1
Correct: C - 16
Rationale:The LCG produces a full period of 16 because the parameters satisfy the
Hull-Dobell theorem: c and m are relatively prime, a-1 is divisible by all prime factors of m,
and a-1 is divisible by 4 since m is a power of 2. For seed 1, the sequence cycles through all
16 values before repeating. Thus, the period is 16.
Q2.
Which of the following approaches is most appropriate for generating a random variate
from a triangular distribution with lower limit a, mode c, and upper limit b?
A. Use the inverse-transform method with a B. Use acceptance-rejection with a uniform
closed-form inverse CDF. proposal distribution.
C. Use convolution of two independent D. Use the Box-Muller transformation.
uniform variates.
Correct: A - Use the inverse-transform method with a closed-form inverse CDF.
Rationale:The triangular distribution has a piecewise linear CDF that can be inverted
analytically, making inverse-transform straightforward and efficient. Acceptance-rejection is
possible but less efficient, convolution of uniforms gives a different distribution (e.g.,
Irwin-Hall), and Box-Muller is for normals.
Q3.
In a terminating simulation of a bank queue, which warm-up period would you recommend
to eliminate initialization bias?
A. No warm-up is needed because the B. Use a warm-up period equal to the mean

C. Use a warm-up period based on Welch's D. Use a warm-up period of zero since
graphical method to identify steady-state. terminating simulations have no steady
state.
Correct: C - Use a warm-up period based on Welch's graphical method to identify

steady-state.
Rationale:Even terminating simulations can suffer from initialization bias if starting conditions
(empty and idle) are unrealistic. Welch's method helps determine warm-up length to reduce
bias. A fixed warm-up equal to mean service time is arbitrary, and zero warm-up may
introduce bias.
Q4.
To reduce variance in estimating the mean waiting time in a call center simulation, you run
two replications with antithetic random numbers and obtain sample averages of 12.3 and
14.7 minutes. What is the variance reduction estimator's standard error?
A. 1.2 minutes B. 0.6 minutes
C. 2.4 minutes D. Cannot determine
Correct: B - 0.6 minutes
Rationale:The antithetic estimator averages the two runs: (12.3+14.7)/2 = 13.5. The variance
of the mean is (s^2/n)*(1+) where is the negative correlation. Assuming perfect negative
correlation (=-1), the variance is zero, but in practice, we estimate the standard error as the
sample standard deviation of the paired differences divided by 2, which is |12.3-14.7|/2 = 1.2.
However, the standard error of the mean is typically the standard deviation of the paired
averages, which is 1.2/2 0.85, but since only two runs, we use the difference: (14.7-12.3)/2 =
1.2. Actually, the standard error of the antithetic estimator is the standard deviation of the two
averages divided by 2, which is 1.2/2 0.85. None match, but the correct is 1.2? Let's
compute: sample variance of [12.3,14.7] is ((12.3-13.5)^2+(14.7-13.5)^2)/(2-1)=2.88, so
s=2.88=1.697, SE=1.697/2=1.2. So answer is 1.2.
Q5.
You have 10 independent replications of a simulation, each yielding a sample mean of the
daily profit. The sample variance of the 10 means is 25. What is the standard error of the
overall mean profit?
A. 0.5 B. 1.58
C. 5.0 D. 2.5
Correct: B - 1.58
Rationale:The standard error is the sample standard deviation divided by the square root of
the number of replications: 25/10 = 5/3.162 = 1.58. This reflects the variability of the sample
mean estimate.

To reduce variance in estimating the mean waiting time in a call center simulation, you run
two replications with antithetic random numbers and obtain sample averages of 12.3 and
14.7 minutes. What is the variance reduction estimator's standard error?
A. 1.2 minutes B. 0.6 minutes
C. 2.4 minutes D. Cannot determine

of the mean is (s^2/n)*(1+) where is the negative correlation. Assuming perfect negative
correlation (=-1), the variance is zero, but in practice, we estimate the standard error as the

s=2.88=1.697, SE=1.697/2=1.2. So answer is 1.2.
Q5.
You have 10 independent replications of a simulation, each yielding a sample mean of the
daily profit. The sample variance of the 10 means is 25. What is the standard error of the
overall mean profit?
A. 0.5 B. 1.58
C. 5.0 D. 2.5
Correct: B - 1.58
Rationale:The standard error is the sample standard deviation divided by the square root of
the number of replications: 25/10 = 5/3.162 = 1.58. This reflects the variability of the sample
mean estimate.
