WebStatistics A hypothesis test is to be performed for a population mean with null hypothesis of H0: u=u0 . The test statistic used will be z= x - u0 / o / square root of n.. Find the critical value (s) for a two-tailed test with α = 0.02 and draw a graph that illustrates your answer.

The power of a hypothesis test is between 0 and 1; if the power is close to 1, the hypothesis test is very good at detecting a false null hypothesis. Beta is commonly set at 0.2, but may be set by the researchers to be smaller. Consequently, power may be as low as 0.8, but may be higher. rudish definition
