Question

Nagy et al. (A-27) studied 50 stable patients who were admitted for a gunshot wound that traversed the mediastinum. Of these, eight were deemed to have a mediastinal injury and 42 did not. The standard deviation for the ages of the eight subjects with mediastinal injury was 4.7 years, and the standard deviation of ages for the 42 without injury was 11.6 years. Can we conclude from these data that the variance of age is larger for a population of similar subjects without injury compared to a population with mediastinal injury? Let α = .05.
