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, 7.0 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 six minutes each. Assume the queue
length can be infinite with the 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? (Do not round your
intermediate calculations. Round your answer to 3 decimal
places.)
c. What is the average amount of time that
a person can expect to spend in line? (Do not round
your intermediate calculations. Round your answer to 4 decimal
places.)
d. On average, how much time will it take
to measure a person’s blood pressure, including their waiting
time? (Do not round your intermediate calculations.
Round your answer to 4 decimal places.)
