# Poisson Tests One-Sample

The One-sample Poisson Test test is used to test if the sample was drawn from a population with a Poisson Rate equal to some hypothesized value. Exact Poisson tests are performed.

## Hypotheses

The following hypotheses may be tested:

Where is the true population Rate from which the sample was drawn, and is the hypothesized population value.

## Assumptions

- The sample has been randomly drawn from the population (Critical)
- The population may be modeled with a Poisson distribution (Critical)

## Test Statistics

## Output

### Note

The p-value is flagged with an asterisk (*) when p <= alpha.
