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, 7 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.

B) What average number of persons can be expected to be in the system? (round answer to 4 decimals)
C) What is the average amount of time that a person can expect to spend in line?(round answer to 4 decimals)
D) On the average, how much time will it take to measure a person's blood pressure, including waiting time?(round answer to 4 decimals))
