Question

The Cornbread Cafe in Eugene, Oregon, recently installed a new computer system that allows customers to order their meals electronically from their tables. The manager of the restaurant claims that this new system will decrease the waiting time, and that the probability of getting a meal in less than 77 minutes (with this system in place) is 0.75.0.75. Suppose four customers are selected at random. Let the random variable ?X be the number of customers who get their meal in less than 7 minutes.7 minutes.

Find the probability distribution for ?.X. Round your answers to four decimal places.

P(0) =

p(1) =

P(2) =

P(3) =

P(4) =

Answer #1

. Recall that a bank manager has
developed a new system to reduce the time customers spend waiting
for teller service during peak hours. The manager hopes the new
system will reduce waiting times from the current 9 to 10 minutes
to less than 6 minutes.
Suppose the manager wishes to use the
random sample of 75 waiting times to support the
claim that the mean waiting time under the new system is shorter
than six minutes.
Letting μ represent...

4. A bank manager has developed a new system to reduce the time
customers spend waiting for teller service during peak hours. The
manager hopes that the new system will reduce waiting times from
the current 9 to 10 minutes to less than 6 minutes. a. Set up the
null and alternative hypotheses needed if we wish to attempt to
provide evidence supporting the claim that the mean waiting time is
shorter than six minutes. b. The mean and the...

Willow Brook National Bank operates a drive-up teller window
that allows customers to complete bank transactions without getting
out of their cars. On weekday mornings, arrivals to the drive-up
teller window occur at random, with an arrival rate of 30 customers
per hour or 0.5 customers per minute. In the same bank waiting line
system, assume that the service times for the drive-up teller
follow an exponential probability distribution with a service rate
of 36 customers per hour, or 0.6...

Recall that a bank manager has developed a new system to reduce
the time customers spend waiting to be served by tellers during
peak business hours. The mean waiting time during peak business
hours under the current system is roughly 9 to 10 minutes. The bank
manager hopes that the new system will have a mean waiting time
that is less than six minutes. The mean of the sample of 104 bank
customer waiting times is x¯x¯ = 5.46. If...

Problem 15-3 (Algorithmic) Willow Brook National Bank operates a
drive-up teller window that allows customers to complete bank
transactions without getting out of their cars. On weekday
mornings, arrivals to the drive-up teller window occur at random,
with an arrival rate of 18 customers per hour or 0.3 customers per
minute. In the same bank waiting line system, assume that the
service times for the drive-up teller follow an exponential
probability distribution with a service rate of 30 customers per...

1. A Telecommunications company recently installed a new speech
recognition system for its repair calls. In their old system,
operators had to press keys on the numeric keypad to answer
questions, which led to longer time on service calls.
The company is conducting a study to determine the effectiveness
of the new system and to do so they want to estimate the average
duration of service calls with the new system.
They analyzed a random sample of 15 service calls...

1. Willow Brook National Bank operates a drive-up teller window
that allows customers to complete bank transactions without getting
out of their cars. On weekday mornings, arrivals to the drive-up
teller window occur at random, with an arrival rate of 6 customers
per hour or 0.1 customers per minute. Also assume that the service
times for the drive-up teller follow an exponential probability
distribution with a service rate of 54 customers per hour, or 0.9
customers per minute. Determine the...

8.27. The PNC bank manager of WMU branch has developed a new
system to reduce the time customers spend waiting for teller
service during peak hours. The manager hopes the new system will
reduce waiting times from the current nine to ten minutes to less
than 6 minutes.Average waiting time was obtained as 5.46 based on a
random sample of 25 waiting times. Is there enough evidence at the
5% level of significance to validate managers claim? Assume that
the...

Willow Brook National Bank operates a drive-up teller window
that allows customers to complete bank transactions without getting
out of their cars. On weekday mornings, arrivals to the drive-up
teller window occur at random, with an arrival rate of 24 customers
per hour or 0.4 customers per minute. Also assume that the service
times for the drive-up teller follow an exponential probability
distribution with a service rate of 36 customers per hour, or 0.6
customers per minute. Determine the probabilities...
