Transcribed Image Text:Customers arrive at a suburban ticket outlet at the rate of
14 per hour on Monday mornings. This can be described
by a Poisson distribution. Selling the tickets and providing
general information takes an average of 3 minutes per
customer, and varies exponentially. Determine average
time in line and average time in the system.
Select one:
O a. Average time in line 4 minutes and average time
in the system 7 minutes
O b. Average time in line 7 minutes and average time
in the system 10 minutes
O c. Average time in line 2 minutes and average time
in the system 5 minutes
O d. Average time in line 3 minutes and average time
in the system 6 minutes
