7) The operations manager of a body and paint shop has five cars to schedule for repair.
He would like to minimize the throughput time to complete all work on these cars. Each
car requires body work prior to painting. The estimates of the times required to do the
body paint work on each are as follows:

9) A restaurant at a popular Colorado casino provides priority service to player's card
holders. The restaurant has 10 tables or booths where customers may be seated. The
service time (time a booth or table is occupied) averages 40 minutes once a party is
seated. The customer arrival rate is 12 parties per hour, with the parties being equally
divided between card holders and people without player's cards. On average, how much
longer do parties without player's cards spend in the system, compared to parties with
the player's cards?
A.2 minutes
B.4 minutes
C.8 minutes
D.10 minutes
E.It is impossible to say without more information.
10) The operations manager for a well-drilling company must recommend whether to
build a new facility, expand his existing one, or do nothing. He estimates that long-run
profits (in $000) will vary with the amount of precipitation (rainfall) as follows:

and 50 percent respectively, what are expected long-run profits for the alternative he
will select?
A.$140,000
B.$170,000
C.$285,000
D.$305,000
E.$475,000

13) One local hospital has just enough space and funds currently available to start either
a cancer or heart research lab. If administration decides on the cancer lab, there is a 20
percent chance of getting $100,000 in outside funding from the American Cancer
Society next year, and an 80 percent chance of getting nothing. If the cancer research
lab is funded the first year, no additional outside funding will be available the second
year. However, if it is not funded the first year, then management estimates the chances
are 50 percent it will get $100,000 the following year, and 50 percent that it will get
nothing again. If, however, the hospital's management decides to go with the heart lab,
then there is a 50 percent chance of getting $50,000 in outside funding from the
American Heart Association the first year and a 50 percent change of getting nothing. If
the heart lab is funded the first year, management estimates a 40 percent chance of
getting another $50,000 and a 60 percent chance of getting nothing additional the
second year. If it is not funded the first year, then management estimates a 60 percent
chance for getting $50,000 and a 40 percent chance for getting nothing in the following
year. For both the cancer and heart research labs, no further possible funding is
anticipated beyond the first two years.
What is the expected value for the optimum decision alternative?
A.$100,000
B.$60,000
C.$50,000
D.$40,000
E.$20,000

considered.
