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, 13.0 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 four 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 3 decimal places.)
b. What average number of persons can be expected to be in the system? (Round your answer to 3 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.)
All the parts have been done as shown. If there is any rounding off error in part (b) or (d), let me know in the comment section. Thank you.
