LEt X have a Poisson distribution with mean = 4. Show that

P(u -2sigma < X < u +2sigma) = .931

anyone know how i should go about starting this problem? stumped.

What is the CDF and standard deviation of the Poisson distribution?

moo, I mean

So calculate for a Poisson with moo=4.

which is F(11) btw.
