Question

Please solve using **EXCEL** and show steps.

In the Northwest Bank waiting line system, assume that the service times for drive-up teller follow an exponential probability distribution with a mean of 100 customers per hour. Use the exponential probability distribution to answer the following questions:

a. What is the probability that the service time is one minute or less?

b. What is the probability that the service time is two minutes or less?

c. What is the probability that the service time is more than two minutes?

d. What is the probability that the service time is between three and seven minutes?

Need to interpret the results for these problems; if you are unsure of the direction the question asks (left tail, right tail, etc.), draw a diagram.

Answer #1

Exponential/Poisson
Megacity Bank operates a drive-up teller window that
allows customers to complete bank transactions without having to
get out of their car. Megacity Bank waiting line times follow an
exponential distribution with a service rate of 36 customers per
hour.
A.What is the probability that the time to service is 1 minute
or less? (show your formula with the numbers plugged in, as well as
the answer. You may use the e^(-λ) table, an advanced calculator or
excel to...

Question 2
A fast-food franchise is considering
operating a drive-up window food-service operation. Assume that
customer arrivals follow a Poisson probability distribution, with
an arrival rate of 24 cars per hour, and that service times follow
an exponential probability distribution. Arriving customers place
orders at an intercom station at the back of the parking lot and
then drive to the service window to pay for and receive their
orders. The following three service alternatives are being
considered:
A single-channel operation...

Bank A and Bank B have each developed an improved process for
serving customers. The waiting period from the moment a customer
enters until he or she reaches the counter needs to be shortened. A
random sample of 10 customers is selected from each bank and the
results (in minutes) are shown in the accompanying data table.
