Suppose that there are two supervisors at Kardashian restaurant (Kim and Kylie), and the # of customer complaints differs based on the supervisor on duty. This is determined according to aPoisson process. The quality of service of one day does NOT affect the quality of service on the next day.
|
Supervisor on duty: |
Average # of customer complaints (per day): |
Days on duty (out of 5 days): |
|
Kim |
2 per day |
2 out of 5 days |
|
Kylie |
3 per day |
3 out of 5 days |
Answer the following questions based on the information given above:
* please don’t copy other experts’ answer
i) Assuming that Kylie is on duty, solve for the expected # of customer complaints in the next 2 days.
ii) Assuming that Kylie is on duty, solve for the probability that there will be no customer complaints tomorrow.
iii) If there was AT LEAST 1 customer complaint yesterday, what's the probability that Kim was on duty?
iv) Solve for the probability that there will be no customer complaints in the next 2 days.

A cell phone manufacturer has noticed that the number of faulty cell phones detected in a production run only depends on the supervisor on duty and is detected according to a Poisson Process. There are only 2 supervisors: James and Russell, in the firm. The average number of faulty cell phones is two per day when James is on duty, while the average number of faulty cell phones is three per day when Russell is on duty. It is also...

(2.90 One of the major measures of the quality of service pro- vided by an organization is the speed with which the organi- zation responds to customer complaints. A large family-held department store selling furniture and flooring, including car- pet, had undergone a major expansion in the past several years. In particular, the flooring department had expanded from 2 in- stallation crews to an installation supervisor, a measurer, and 15 installation crews. A business objective of the company was to...

A Fast Food drive-through Restaurant with a single check-out counter opens six days a week, but its heaviest day of business is on Saturdays. Customers arrive at an average rate of 20 per hour on Saturdays. Customers can be provided service at the rate of one every two minutes. Assuming Poisson arrivals and exponential service times, find: The average number of customers in line The average time a car waits before being served The average time a customer spends in...
