The Heart Association plans t install a free blood pressure testing booth at the Palouse mall for a week. Previous experience indicates that, on average, 10 persons per hour request a test and the arrivals are Poisson distributed from an infinite population. Blood pressure measurements are exponential with an average time of 5 minutes per exam.

a. What is the average number of people in line (2 pts)?

b. What is the average number of people in the system (2 pts)?

c. What is the average amount of time a person can expect to spend in line (2 pts)?

d. What is the average amount of time it will take to measure a person’s blood pressure, including waiting in line (2 pts)?

e. What is the probability of having 3 people in line (2 pts)

Use the following information to answer the next few questions: An immigration agent at Ataturk airport in Istanbul, Turkey on the average could process 120 entrants during an 8 hour shift, if she was busy all the time. The number of arrivals is based on a Poisson distribution and the time to process each entrant is a random variable with an exponential distribution. On the average, an entrant arrives at her station once every 6 minutes. Determine the average number...
