what is the statistical definition or meaning of rejection region and the critical value when testng a hypothesis?
----
When estimating a population parameter by sampling,
the conclusion is never absolutely perfect.
The critical value establishes a benchmark and rejection
region(s). so a conclusion can be given with some level
of statistical significance.
