Previous experience indicates that, on the average, 15 people per hour request a test. Assume arrivals follow a Poisson distribution. Each blood pressure measurement takes a variable amount of time, which is assumed to follow an exponential distribution. On average it takes three minutes to check each person.

a. What average number in line can be expected?
b. What average number of persons can be expected to be in the system?
c. What is the average amount of time that a person can expect to spend in line?
d. On the average, how much time will it take to measure a person's blood pressure, including waiting time?
e. On weekends, the arrival rate can be expected to increase to over 12 per hour. What effect will this have on the number in the waiting line?
