Question

The number of trees per acre in the Lassen National Forest in California follows a Poisson distribution with a rate of 100 trees per acre. Let the random variable X count the number of trees per randomly selected acre of the Lassen National Forest

A) State the distribution of the randomly variable defined above

B) Compute and interpret P(X=107)

C) Compute the probability that in a randomly selected acre of the Lassen National Forest there are at most 90 trees

D) Compute the probability that in a randomly selected acre of the Lassen National Forest there are more than 105 trees

E) Compute the probability that in a randomly selected acre of the Lassen National Forest there are exactly 100 trees

F) Using the mean and standard deviation, describe the number of trees in a typical acre of the Lassen National Forest

In one town, the number of burglaries in a week has a Poisson
distribution with mean μ = 4.5. Let variable x denote the number of
burglaries in this town in a randomly selected
month. Find the smallest
usual value for x. Round your answer to three
decimal places.
(HINT: Assume a month to be exactly 4 weeks)

Suppose that the number of eggs that a hen lays follows the
Poisson distribution with parameter λ = 2. Assume further that each
of the eggs hatches with probability p = 0.8, and different eggs
hatch independently. Let X denote the total number of
survivors.

(ii) What is the probability that there is an even number of
survivors?
(iii) Compute the probability mass function of the random
variable sin(πX/2) and its expectation.
