Pickson Luthiers Corporation is studying where to locate a phone charging point on the
factory floor. The locations of five production cells are expressed as X– and
Y-coordinates on a rectangular grid of the factory layout. The daily demand for the
charging point (measured as the number of trips to the charging point) at each
production cell is also known. Because of the nature of the equipment layout in the
factory and for safety reasons, workers must travel along marked horizontal and vertical
aisles to access the charger. Thus, the distance from a cell to the charger is measured as
rectilinear distance.
The table below provides the relevant information.
The optimal location should minimize the total weighted distance between the charging
point and all production cells, where the weights are the daily number of trips to the
phone charging point.
According to the model, which of the following is the weighted distance between the
phone charger and Electricals cell?
A) 75.00
B) 125.00
C) 100.00
D) 112.50

The Riviera Transport Company (RTC) produces car accessories at two plants: Dallas
and Atlanta. They ship them to major distribution centers in Houston, San Jose,
Jacksonville, and Memphis. The accounting, production, and marketing departments
have provided the information in the table below, which shows the unit cost of shipping
between any plant and distribution center, plant capacities over the next planning
period, and distribution center demands. RTC’s supply chain manager faces the problem
of determining how much to ship between each plant and distribution center to
minimize the total transportation cost, not exceed available capacity, and meet customer
demand.
Assume Xij = amount shipped from plant i to distribution center j, where i = 1
represents Dallas, i = 2 represents Atlanta, j = 1 represents Houston, and so on.
From the Sensitivity Report on the model, to which of the following cities can Atlanta
not ship to without reducing unit cost of production?
A) Houston
B) San Jose
C) Jacksonville
D) Memphis

Dresden Pharmaceuticals has decided to go ahead and start clinical trials on a potential
new drug. The total R&D costs are estimated to reach around $875,000,000 with
clinical trials mounting to $145,000,000. The current market size is estimated to be
around 3,000,000 and is expected to grow at 4 percent every year. The market share
Dresden hopes to capture in the first year is 7 percent, and is projected to grow by 25
percent each year for the next 4 years. A monthly prescription is anticipated to generate
revenue of $420 while incurring variable costs of $150. A discount rate of 8 percent is
assumed.
Calculate the annual revenue for the fourth year.
A) $ 2,325,304,800
B) $830,466,000
C) $1,494,838,800
D) $1,149,876,000
Which of the following is the initial step in conducting a hypothesis test?
A) collecting data and calculating a test statistic
B) selecting a level of significance
C) identifying the population parameter of interest
D) determining a decision rule

$4,900 million and a standard deviation of $1,000 million; if market is medium, payoff
is lognormally distributed with a mean of $2,500 million and a standard deviation of
$500 million; and if market is small, payoff is normally distributed with a mean of
$1,800 million and standard deviation of $200 million. Let us also assume that the cost
of clinical trials is uncertain and estimates are modeled with a triangular distribution
with a minimum of -$ 700 million, a most likely value of – $550 million, and a
