Suppose that the amount of service(ordering a coffee and getting it done) time at a KU driving- through coffee shop is exponentially distributed with an expected value of 10 minutes. You arrive at the driving-through line while one customer is being served and one other customer is waiting in the line. The staff of the coffee shop informs you that the customer has already ordered a Cafe Latte and waited for 5 minutes. What is the probability that the customer...

Customer Service. A customer service department asks its customers to rate their over-the-phone service on a scale of 1-20 immediately after their service has been completed. The department then matches each customer’s rating with the number of minutes the person waited on hold. The file “Hold” on d2l contains data for the ratings and number of minutes on hold for 20 customers. As demonstrated in the lecture, please create a subset data of size 16 and perform your statistical analysis...

Customers arrive at a service facility according to a Poisson process of rate 5/hour. Let N(t) be the number of customers that have arrived up to time t (t hours) a. What is the probability that there is at least 2 customer walked in 30 mins? b. If there was no customer in the first 30 minutes, what is the probability that you have to wait in total of more than 1 hours for the 1st customer to show up?...

An Internet service provider company has installed a modem to serve the needs of 1 customer in an arbitrary region Suppose that once a connection service is requested by a customer, one unassigned modem must be immediately assigned to the customer or the request will be denied At each time period, a customer may request for a connection service with a probability of 0.7 a. What is the probability distribution of a customer request for a connection? It suffices to...

A customer service department and is customers to sate their own the phone service on a scale of 1-20 immediately after their service has been completed. The department than matches each customers rating with the number of minutes the person walled on hold. The accompanying table shows the ratings and number of minutes on hold for 10 randomly selected customers. The regression line for the data is = 16.8427 -0.3701x47x30 and 50.9876 Complete parts a through below B Click the...

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...
