or
Option C is correct
Answer:
A. 0.199
B. 0.199
C. 6.0000
Step-by-step explanation:
Using the poisson distribution
f(x) = (e^-ht × (ht)^x)/x!
Where h = 3, t = 1 min
f(x) = [e^-(3× 1) ×(3×1)^x]/x!
f(1) = [e^-3 (3)]/1! = 3e^-3
= 0.1991
f(1)= 0.199
h = mean = np = 1 × 0.1991 = 0.1991
(b) for Poisson distribution
mean = standard deviation = h
h = np = 0.199
(c) we want to find x for
f(x) = P(X<x) = 0.95
So we check from the Poisson table the value of x for h= 3 gives a probability of 0.95
P(X< 6) = 0.95(approximately)
X = 6.0000
