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 the average, 14 persons per hour request a test. Assume arrivals are Poisson from an infinite population. Blood pressure measurements can be made at a constant time of two minutes each. Assume the queue length can be infinite with FCFS discipline.
a. What average number in line can be expected? (Round your answer to 4 decimal places.)
b. What average number of persons can be expected to be in the system? (Round your answer to 4 decimal places.)
c. What is the average amount of time that a person can expect to spend in line? (Round your answer to 4 decimal places.)
d. On the average, how much time will it take to measure a person's blood pressure, including waiting time? (Round your answer to 4 decimal places.)
