Previous experience indicates that, on average, 16 persons per hour request a test. Assume arrivals are Poisson distributed from an infinite population. Blood pressure measuremients can be made at a constant time of three minutes each. Assume the queue length can be infinite with FCFS discipline. can be intinite 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. Whot is the average amount of time a person can expect to spend in line? (Round your answer to 4 decimal places.) d. On averape, how much time wili it take to measure a person's blood pressure, including wating time? (Round your answer to 4 decimal places.)
