20. An engineer builds a simulation model of a small
factory, runs an experiment with the model using
15 replicates, and determines, at a 90% confidence
= level, that the mean time an entity spends in the sys-
tem is 24-28 min. Based on this information, which of
the following is a reasonable assumption about the
entity time-in-system?
(A) The population mean time-in-system must be in
the interval of 24-28 min.
(B)
(C)
The largest mean time-in-system for any one of
the 15 replicates is 28 min.
If the engineer were to run a 16th replicate, the
mean time-in-system for that replicate would be
in the interval of 24-28 min.
(D) The probability that the population mean time-
in-system is greater than 28 min can be esti-
mated as 5%.
