In: Statistics and Probability
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
μ = 8t.
(Round your answers to three decimal places.)
(a)
What is the probability that exactly 6 small aircraft arrive during a 1-hour period?
What is the probability that at least 6 small aircraft arrive during a 1-hour period?
What is the probability that at least 11 small aircraft arrive during a 1-hour period?
(b)
What is the expected value and standard deviation of the number of small aircraft that arrive during a 90-min period?
expected value standard deviation
(c)
What is the probability that at least 23 small aircraft arrive during a 2.5-hour period?
What is the probability that at most 15 small aircraft arrive during a 2.5-hour period?
