Suppose you are considering whether to go to Paris with a group
of friends
during your Christmas holiday. The round trip airfare from Hong
Kong to
Paris is $12,000, but you have an option to pay this airfare
with a frequent-
flyer coupon. All other relevant costs of the vacation in Paris add
up to

You are the manager of a restaurant for a fast-food franchise.
Last month, the mean waiting time at the drive-through window for
branches in your geographical region, as measured from the time a
customer places an order until the time the customer receives the
order, was 3.6 minutes. You select a random sample of 81 orders.
The sample mean waiting time is 3.79 minutes, with a sample
standard deviation of 0.9 minute. At the 0.10 level of
significance, is there...

Two friends are deciding where to go for dinner. There
are three choices, which we label A, B, and C. Max prefers A to B
to C. Sally prefers B to A to C. To decide which restaurant to go
to, the friends adopt the following procedure:
First, Max eliminates one of three choices.
Then, Sally decides among the
two remaining choices.
Thus, Max has three strategies
(eliminate A, eliminate B, and eliminate C). For each of those
strategies,...

Suppose a restaurant determines that their daily profits are
approximately normally distributed with a mean of μ = $1500 and a
standard deviation of σ = $1050.
What is the probability that the restaurant makes a profit each
day? In other words, what is the probability that the restaurant’s
daily profit is at least one cent?
Assuming that the standard deviation stays the same, what daily
mean would be re- quired for there to be a 99% chance that the...

Last year, you and two friends from college purchased a food
truck for $70,000 hoping to make
it big selling breakfast tacos. Your tacos were a big hit, and

your business (truck, name, and all equipment) for $100,000
today (2020). Over the next 5 years,
you project annual revenue to be $50,000 with operating costs
of $10,000. Escalation of revenue
and operating costs are expected to be a washout. The MACRS
