A coin-operated soft drink machine was designed to discharge, on average, 12 ounces of beverage per cup. In a test of the machine, ten cupfuls of beverage were drawn from the machine and measured. The mean and standard deviation of the ten measurements were 12.1 ounces and 0.12 ounce, respectively. Do these data present sufficient evidence to indicate that the mean discharge differs from 12 ounces? Test using a 0.10. Step 1 of 3: What is the rejection rule using the critical value?
