Suppose small aircraft arrive at a certain airport according to a Poisson process with rate α= 8 per hour

Suppose small aircraft arrive at a certain airport according to a Poisson process with rate α= 8 per hour, so that the number of arrivals during a time period of t hours is a Poisson rv with parameter λ = 8t. (a) What is the probability that exactly 6 small aircraft arrive during a 1-hour period? At least 6? At least 10? (b) What are the expected value and standard deviation of the number of small aircraft that arrive during...

Cars arrive at a parking lot at a rate of 20 per hour. Assume that a Poisson process model is appropriate. Answer the following questions. No derivations are needed but justification of your answers are necessary. What assumptions are necessary to model the arrival of cars as a Poisson process? What is the expected number of cars that arrive between 10:00 a.m and 11:45 a. m? Suppose you walk into the parking lot at 10:15 a.m.; how long, on average,...
