Problem 7-18 (Algo)

To support National Heart Week, the Heart Association plans to install a free blood pressure testing booth in El Con Mall for the week. Previous experience indicates that, on average, 15.0 persons per hour request a test. Assume arrivals are Poisson distributed from an infinite population. Blood pressure measurements can be made at a constant time of three minutes each. Assume the queue length can be infinite with the FCFS discipline.

a. What average number in line can be expected? (Round your answer to 3 decimal places.)

b. What average number of persons can be expected to be in the system? (Do not round your intermediate calculations. Round your answer to 3 decimal places.)

c. What is the average amount of time that a person can expect to spend in line? (Do not round your intermediate calculations. Round your answer to 4 decimal places.)

d. On average, how much time will it take to measure a person’s blood pressure, including their waiting time? (Do not round your intermediate calculations. Round your answer to 4 decimal places.)
