The time between arrivals of cars at the Petroc Services Station is defined by the following probability distribution:

a. Simulate the arrival of cars at the service station for 20 arrivals and compute the average time between arrivals.

b. Simulate the arrival of cars at the service station for 1 hour, using a different stream of random numbers from those used in (a) and compute the average time between arrivals.

c. Compare the results obtained in (a) and (b).
