Customers enter the camera department of a store at an average
rate of five per hour. The department is staffed by one employee,
who takes an average of 8.0 minutes to serve each arrival. Assume
this is a simple Poisson arrival, exponentially distributed service
time situation. (Use the Excel spreadsheet Queue Models.)
a-1. As a casual observer, how many people would
you expect to see in the camera department (excluding the clerk)?
(Round your answer to 2 decimal places.)
a-2. How long would a customer expect to spend in the camera department (total time)? (Do not round intermediate calculations. Round your answer to 1 decimal place.)
b. What is the utilization of the clerk? (Do not round intermediate calculations. Round your answer to 1 decimal place.)
c. What is the probability that there are more than two people in the camera department (excluding the clerk)?(Do not round intermediate calculations. Round your answer to 1 decimal place.)
d. Another clerk has been hired for the camera department who also takes an average of 8.0 minutes to serve each arrival. How long would a customer expect to spend in the department now? (Do not round intermediate calculations. Round your answer to 1 decimal place.)

The first three answers are correct. Need the final two.
Problem 10-16 Customers enter the camera department of a store at the average rate of nine per hour. The department is staffed by one employee, who takes an average of 3.0 minutes to serve each arrival. Assume this is a simple Poisson arrival, exponentially distributed service time situation. Use Exhibit 10.9. a-1. As a casual observer, how many people would you expect to see in the camera department (excluding the...

Customers enter the camera department of a store with an average of 14.46 minutes between customers. The department is staffed by one employee, who can handle an average of 11.76 customers per hour. Assume this is a simple Poisson arrival, exponentially distributed service time situation. Find the following information to help the manager decide if a second employee should be added: 1) The average number of customers waiting. Please keep 4 decimals. 2)The average time a customer waits (in minutes)....

Students arrive at the Administrative Services Office at an average of one every 24 minutes, and their requests take on average 20 minutes to be processed. The service counter is staffed by only one clerk, Judy Gumshoes, who works eight hours per day. Assume Poisson arrivals and exponential service times. a. What percentage of time is Judy idle? (Round your answer to 1 decimal place.) Percentage of time --------------% b. How much time, on average, does a student spend waiting...

customers arrive at an average of 30 per hour. A single server in the store serves customers, taking 1.5 minutes on average to serve each customer. Inter-arrival times and service times follow the exponential distribution. What is the expected fraction of time that the server will be busy? On average, how many people will there be in the store? On average, how long will someone be in the store? What is the probability that there will be more than 2...

In serving themselves, customers take about 12 seconds, exponentially distributed. a. How many customers would you expect to see on the average at the coffee urn? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Average no of customers b. How long would you expect it to take...

Benny the Barber owns a one-chair shop. At barber college, they told Benny that his customers would exhibit a Poisson arrival distribution and that he would provide an exponential service distribution. His market survey data indicate that customers arrive at a rate of 2.0 per hour. It will take Benny an average of 22 minutes to give a haircut. Based on these figures, find the following: a. The average number of customers waiting. (Round your intermediate calculations to 3 decimal...
