Question
I only need help with part (e). Thank you!
The result of the previous problem might be useful for part (e).] Suppose the occurrence of a rare disease in a certain population is known to follow a Poisson distribution, with an average of lambda = 2.3 cases per year. In a typical year, what is the probability that... no cases occur? exactly one case occurs? exactly two cases occur? three or more cases occur? Answer (a)-(d) for a typical two-year period. (Assume independence from year to year.) Use the function dpois in R to redo (a), (b), and (c), and include the output as part of your submitted assignment, dearly showing agreement of your answers. Use the function ppois in R to redo (d), and include the output as part of your submitted assignment, clearly showing agreement of your answer.Explanation / Answer
25e).
=2.3 cases per year
There fore =4.6 cases per two year
a)..P( x=0)= 0.0101
b)..P( x=1)= 0.0462
c)..P( x=2)= 0.1063
d)..P( x 3)= 0.8374
