Again, using the critical xbar method, the critical z-value is -1.645. From the equation you get -1.645= (critical xbar-50)/ (5/6), and solving this for the critical xbar results in critical ...

This article introduces a novel hybrid method for computing p-values of exact tests by combining Monte Carlo simulations and statistical tables generated a priori. To use the data from Monte Carlo ...

This paper presents a fast simple method of calculating exact p values and critical values and uses the method to evaluate the accuracy of the various approximations. Econometric Theory provides an ...
