at CNG gas station, on average 3 CNG operated buses arrive every 15 minutes. what kind of probability distribution would be suitable to describe the number of buses arriving? Also , find the probability that during a sample 15 minutes confirming to this distribution the probability of 2 buses would arrive at the gas station
Homework Answers
Mean = 3 buses every 15 minutes
This is a Poisson distribution.
mu = 3
P(X = x) = e-3 * 3x / x!
P(X = 2) = e_3 * 32 / 2! = 0.0747 (ans)

3. Buses arrive at a specified stop at 15-minute intervals starting at 7 A.M. That is, they arrive at 7, 7:15, 7:30, 7:45, and so on. If a passenger arrives at the stop at a time that is uniformly distributed between 7 and 7:40, find the probability that he waits more than 10 minutes for a bus.

Customers arrive randomly at a gas station at the average rate of 30 per hour, while attendants can handle transactions on an average time of 5 minutes each (with exponential distribution). If a clerk cost is $15 per hour and customer waiting time represents a cost of $10 per hour, how many clerks can be justified on a cost basis?

Students arrive at the Administrative Services Office at an average of one every 24 minutes, and their requests take on average 20 minutes to be processed. The service counter is staffed by only one clerk, Judy Gumshoes, who works eight hours per day. Assume Poisson arrivals and exponential service times. a. What percentage of time is Judy idle? (Round your answer to 1 decimal place.) Percentage of time --------------% b. How much time, on average, does a student spend waiting...

Assume that for a gas and car wash station one car can be serviced at a time. The arrivals follow a Poisson probability distribution, with an arrival rate of 1 car every 10 minutes and the service times follow an exponential probability distribution, with a service rate of 8 cars per hour. What is the probability that the station will be idle? What is the average number of cars that will be waiting for service? What is the average time...
