ISYE 6644 - Final EXAM
ISYE 6644 - Final EXAM
ISYE 6644 - Final EXAM
CORRECT ANSWER
ISYE 6644 - Final EXAM
RATIONALE
The reference to "ISYE 6644 - Final EXAM" indicates a specific course and examination context, emphasizing the importance of
understanding the subject matter and requirements associated with that particular course. Recognizing course identifiers is
critical for contextualizing academic assessments and aligning study strategies accordingly.
Q2 QUESTION 2 OF 114
Suppose that a Bernoulli selection procedure tells you to take 100 observations from each of two populations, A and
B. It turns out that A gets 85 successes and B gets 46 successes. What do you think?
CORRECT ANSWER
1) A almost certainly has a higher success probability than B.
2) We could've probably stopped sampling a bit earlier (i.e., with fewer than 100 observations) because A was so far
ahead of B.
RATIONALE
The substantial difference in observed successes indicates a likely higher success probability in population A, as the law of
large numbers suggests that larger sample sizes converge to the true population parameters. Additionally, the early
dominance of A's success rate implies that fewer observations could have sufficed to infer its superiority over B.
Q3 QUESTION 3 OF 114
Suppose that we want to know which of Coke, Pepsi and Dr.pepper is the most popular. We would like to make the
correct selection with probability of at least P=0.90 in the event that the ration of the highest-to-second-highest
Page 2
,preference probabilities happens to be at least 0=1.4. How many people does the single-stage procedure Mbem
require us to interview?
CORRECT ANSWER
126
Go to the table in the notes and pick off the entry for k=3, P^⋆=0.90, and θ^⋆=1.4.
RATIONALE
90 in accurately identifying the most popular beverage among three options, the sample size must account for the specified
ratio of preference probabilities, using established statistical methods that consider the worst-case scenario of preference
distribution. Consulting the relevant statistical table for three choices at the given parameters yields a required sample size of
126 participants.
Q4 QUESTION 4 OF 114
TRUE or FALSE? The common random numbers technique intentionally induces positive correlation between two
systems - much like a paired-𝑡confidence interval.
CORRECT ANSWER
TRUE
RATIONALE
Common random numbers enhance the correlation between two systems by using the same random sample for both, thereby
reducing variability in comparative analysis, akin to how a paired t-test controls for individual differences. This technique
strengthens the statistical validity of inferences made between the systems being analyzed.
Q5 QUESTION 5 OF 114
CRN depends on someone's ability to manipulate the underlying pseudo-random numbers - e.g., use the same arrival
times when simulating two competing simulated systems. So who ultimately controls those PRNs??
CORRECT ANSWER
You do - you are powerful!
RATIONALE
Control over pseudo-random numbers (PRNs) allows for manipulation of simulation parameters, enabling consistent arrival
times across competing systems, which is critical for comparative analysis. This agency empowers the practitioner to refine
simulations and obtain reliable, reproducible results.

, Q6 QUESTION 6 OF 114
TRUE or FALSE? The antithetic random numbers technique intentionally induces negative correlation between two
runs of the same system - this allows us to better estimate the mean of the system.
CORRECT ANSWER
TRUE
RATIONALE
Antithetic random numbers reduce variance by generating negatively correlated pairs, which helps to stabilize mean
estimates by offsetting high and low values in simulations. This variance reduction technique enhances the accuracy of
statistical estimations in modeling the system's behavior.
Q7 QUESTION 7 OF 114
TRUE or FALSE? The control variates technique provides unbiased, low-variance estimates using a method
reminiscent of regression.
CORRECT ANSWER
TRUE
RATIONALE
Control variates reduce variance in estimates by leveraging known information from correlated variables, akin to regression
analysis, which enhances the efficiency of the estimator while maintaining unbiasedness. This technique effectively adjusts for
random variability, leading to more reliable statistical inferences.
Q8 QUESTION 8 OF 114
Statistical ranking and selection techniques have been designed to address a variety of comparison problems. Which
ones from the following list?
Find the population having the largest mean.
Find the system with the smallest variance.
Find the alternative with the highest success probability.
Find the most-popular candidate.
All of the above.
CORRECT ANSWER
All of the above.
