1) The naive forecast can serve as a quick and easy standard of comparison against
which to judge the cost and accuracy of other techniques.
2) The sampling distribution can be assumed to be approximately normal even when the
underlying process distribution is not normally distributed.
3) Work sampling provides both quick and accurate estimates of activity times.
4) Productivity tends to be only a very minor factor in an organization's ability to
compete.
5) Decision trees, with their predetermined analysis of a situation, are really not useful
in making health care decisions since every person is unique.
6) The number of defective parts in a sample is an example of variable data because it
will "vary" from one sample to another.

purchased, which is often 60 percent or more of the cost of finished goods.
8) All infinite-source queuing models require the system utilization to be less than 1.0.
