As the population ages, there is increasing concern about the accident-related injuries to the elderly. The article "Age and Gender Differences in Single-Step Recovery from a Forward Fall" reported on an experiment in which the maximum lean angle - the furthest a subject is able to lean and still recover in one step - was determined for both a sample of younger females (21-29 years) and a sample of older females (67-81 years). The following observations were obtained:

Does the data suggest that the population variance for older females is greater than the population variance for younger females? Test the appropriate hypotheses using ? (alpha)=0.10
