True
Price changes are useful for matching the level of demand to the capacity of a facility.
True
The most common tactic to arrange departments in a process-oriented layout is to minimize material handling costs.

True
Unfavorable exchange rates can offset other savings in a location decision.

True
What is the reasoning behind setting the upper and lower control limits plus or minus n3sigma Subscript x overbar from the mean?
We know that 99.73% of natural variation is contained within plus or minus3sigma Subscript x overbar, and thus any data point outside of the limits is likely due to assignable variation

Of the four approaches to capacity expansion, the approach that "straddles" demand:
a. uses incremental expansion. b. works best when demand is not growing but is stable. c. some times leads demand, and at other times lags. d. uses one-step expansion. e. Choices A and C are both correct.
