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, 8 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 five minutes each. Assume the queue length can be infinite with FCFS discipline.

a. What average number in line can be expected?

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 a person can expect to spend in line?(Round your answer to 4 decimal places.)

d. On average, how much time will it take to measure a person's blood pressure, including waiting time?(Round your answer to 4 decimal places.)
