Basic statistical concepts
... Investigation of a single population (one group): • H0 : The mean is equal to a specific number (e.g. mean FEV for boys is µ1 = 1.5) HA : The mean is not equal to a specific number. Comparison of two populations (two groups): • H0 : The means are equal (i.e. µ1 − µ2 = 0) HA : The means are not equal ...
