SpletStep 1: Based on alpha and the alternative hypothesis, find a critical z-value or z-values (1.645 for the example). Step 2: Take the random sample and compute the sample mean, xbar (for example, suppose the sample xbar that you get is 52.3). Step 3: Put xbar along with mu, sigma, and n into . The resulting z-value is called the computed z-value. Splet13. jun. 2014 · Interpret X bar and S chart.
