Hypothesis Testing Question for Rate of Poisson Distribution
Here is a simple example of hypothesis testing for the parameter lambda of a Poisson distribution which I try to go through in detail, highlighting some of the key concepts such as Null and Alternative Hypothesis, Critical Region/Values and Significance Levels.
