1) A c-chart is used to monitor the number of defects per unit for process output.
2) No stopwatch is required in a work sampling study.
3) For purposes of obtaining good time standards using a stopwatch time study, the
analyst should try to avoid having the worker discover he or she is being observed.
4) Firms that wish to do business with the European Community can benefit from
having a quality management system that meets ISO 9000 standards.
5) User instructions and follow-up services after delivery are important elements of
overall product or service quality.
6) The word "technology" is used only to refer to "information technology."
7) Quality at the source means returning all defects to the sourceour vendors.
8) In the area of maintenance, the Pareto phenomenon is reflected in the fact that,
regardless of problem classification, all equipment will justify about the same expense.
9) Measurement of productivity in service is more straightforward than in
manufacturing since it is not necessary to take into account the cost of materials.
10) Control limits tend to be wider for more variable processes.
11) In a single-sampling plan, the entire lot, or batch of items, is accepted or rejected
based upon only one specified sized sample.
12) A tracking signal focuses on the ratio of cumulative forecast error to the
corresponding value of MAD.
13) ERP began in manufacturing organizations but has spread into service
organizations.
14) Carrying cost is a function of order size; the larger the order, the higher the
inventory carrying cost.
15) Stating capacity in dollar amounts generally results in a consistent measure of
capacity regardless of the actual units of measure.

quantity shipped.
B.The cost of goods shipped from any source to any destination is a linear function of
the cost per unit.
C.The total cost associated with a given plan is a linear function of shipping costs.
D.Cell evaluations require linear horizontal movements through the matrix.

B.length of lead time
C.lead time variability
D.stockout risk
E.purchase cost
20) A system consists of two components, each of which must activate if the system is

overall system reliability?
A..99
B..95
C..94
D..90
E.Cannot be determined with this information.
21) A persistent tendency for forecasts to be greater than or less than the actual values is
called:
A.bias.
B.tracking.
C.control charting.
D.positive correlation.
E.linear regression.
22) Essentially, the output of aggregate planning is the:
A.marketing plan.
B.production plan.
C.rough-cut capacity plan.
D.assignment plan.
E.material requirements plan.
23) Two professors at a nearby university want to coauthor a new textbook in either
economics or statistics. They feel that if they write an economics book, they have a 50
percent chance of placing it with a major publisher, and it should ultimately sell about
40,000 copies. If they cannot get a major publisher to take it, then they feel they have
an 80 percent chance of placing it with a smaller publisher, with ultimate sales of
30,000 copies. On the other hand, if they write a statistics book, they feel they have a 40
percent chance of placing it with a major publisher, and it should result in ultimate sales
of about 50,000 copies. If they cannot get a major publisher to take it, they feel they
have a 50 percent chance of placing it with a smaller publisher, with ultimate sales of
35,000 copies.
What is the expected value for the decision alternative to write the statistics book?
A.50,000 copies
B.40,000 copies
C.32,000 copies
D.30,500 copies
E.10,500 copies

have an annual fixed cost of $100,000 and variable costs of $22 per unit. Alternative B
would have annual fixed costs of $120,000 and variable costs of $20 per unit.
