A possible important environmental determinant of lung function in children is amount of cigarette smoking in the home. Suppose this question is studied by selecting two groups: Group 1 consists of 23 nonsmoking children 5-9 years of age with two parents who smoke, and have mean forced expiratory volume (FEV) of 2.1 L and a standard deviation of 0.7 L; group 2 consists of 20 nonsmoking children of comparable age, with two parents who do not smoke, and have mean FEV of 2.3 L and a standard deviation of 0.4 L.

We have no evidence to say that mean forced expiratory volume (FEV) for children with parents who smoke is different than the mean forced expiratory volume (FEV) for children with parents who do not smoke.
