Question 1
What is a possible goal of an indifference-zone normal means
selection technique?
A) Find the normal population having the smallest variance
B) Find the normal population having the largest mean, especially if
the largest mean is ≫ the second-largest
C) Find the normal population having the median closest to zero
D) Find the normal population having the highest kurtosis
E) Find the normal population having the lowest coefficient of
variation
Correct Answer: B
Rationale: The indifference-zone approach for normal means
selection is specifically designed to identify the normal population
with the largest mean, particularly when that mean substantially
exceeds the second-largest mean. This technique ensures the
,probability of correct selection is high when the true difference
between the top two populations exceeds a specified indifference
zone.
Question 2
TRUE or FALSE? The Bechhofer procedure for selecting the normal
population with the largest mean specifies the appropriate number of
observations to take from each competing population, and simply
selects the competitor having the largest sample mean.
A) TRUE
B) FALSE
Correct Answer: A
Rationale: The Bechhofer single-stage procedure is a ranking-and-
selection method that prescribes a fixed sample size for each
population in advance. After collecting the specified number of
observations, the procedure selects the population with the largest
sample mean as the one with the largest true mean.
Question 3
TRUE or FALSE? Sometimes a single-stage procedure like
Bechhofer's is inefficient. In fact, it's possible to use certain sequential
,procedures that take observations one-at-a-time (instead of all at once
in a single stage) to make good selection decisions using fewer
observations.
A) TRUE
B) FALSE
Correct Answer: A
Rationale: Sequential procedures can indeed be more efficient than
single-stage procedures by allowing early stopping when one
population emerges as clearly superior. This adaptive approach often
requires fewer total observations while maintaining the same
probability of correct selection.
Question 4
For which scenario(s) below might it be appropriate to use a
Bernoulli selection procedure?
A) Find the inventory policy having the largest profit
B) Find the drug giving the best chance of a cure
C) Find the maintenance policy having the lowest failure probability
D) Find the scheduling rule that has the best chance of making an
on-time delivery
, E) All three of (b), (c), and (d)
Correct Answer: E
Rationale: Bernoulli selection procedures are appropriate when the
response is binary (success/failure). Scenarios involving cure
probability, failure probability, and on-time delivery probability all
involve Bernoulli outcomes. Profit maximization (a) is typically a
continuous response problem.
Question 5
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?
A) A and B have roughly equal success probabilities
B) A almost certainly has a higher success probability than B
C) B almost certainly has a higher success probability than A
D) The results are inconclusive
E) Both populations have the same success probability
Correct Answer: B
