Question: (DSB). The mean lung capacity for non-smoking males aged 50-59 is 2 liters. An investigator wants to examine if the mean lung capacities are significantly different among former smokers of similar background (i.e., males aged 50-59 who smoked in the past and are not currently smokers). A random sample of 60 former smokers is selected. The following table summarizes the results of the test

Large sample test of $\mu =2$ versus $\mu \ne 2$
