Question: 28
(Choose 1 answer)
Suppose X has a Poisson distribution with a mean of 1000. Use the normal approximation for Poisson
distributions to find P(X <950).
Let
P(Z1.33) 0.9082, P(Z<-1.60) = 0.0548,
P(Z-1.88) 0.0301, P(Z < 2.50) = 0.9938.
A. None of the other choices is correct
B. 0.9082
C. 0.0301
D. 0.0548
E. 0.9938
