## Homework Statement

What kind of equations you'll get when trying to find confidence limits 100(1-a) % for λ in Poisson distribution?

## Homework Equations

Poisson distribution P(X=x) = e

^{-λ}λ

^{x}/ x! (x=0,1,2 ...)

## The Attempt at a Solution

I made an equation as follows:

Ʃ (k = from k

_{0}to n) e

^{-λ}λ

^{k}/ k! = a/2

to solve the confidence limits. Am I doing correct thing here? I cannot solve λ from that equation + I'm not supposed to have infinite sums in my equations... Any help for me?
