Practice
4) USA Today reported that the U.S. (annual) birth rate is about 16 per 1000 people, and the death rate is
about 8 per 1000 people.
(a) Explain why the Poisson probability distribution would be a good choice for the random variable
r= number of births (or deaths) for a community of a given population size.
Because ts
ratio
B = .016
D = .008
(b) In a community of 1000 people, what is the (annual) probability of 10 births? What is the probability
of 10 deaths? What is the probability of 16 births? 16 deaths?
