a. Graph p(x) for x = 0, 1, 2, c, 15.
b. Find μ and σ for x and locate m and the interval μ 2σ on the graph.
c. What is the probability that x will fall within the interval μ 2σ?
ANSWER:
Solution:
Step 1 of 2:
Let x be a random variable that follows a poisson distribution with =5.
- We have to graph P(x) for x=0,1,2,c,15.
- We have to find and for x, and we have to locate the mean and the interval on the graph.
- We have to find the probability that x will fall within the interval .
