Problem 28

As the population ages, there is increasing concern aboutaccident-related injuries to the elderly. The article Ageand Gender Differences in Single-Step Recovery froma Forward Fall (J. of Gerontology, 1999: M44M50)reportedon an experiment in which the maximum leananglethe farthest a subject is able to lean and stillrecover in one stepwas determined for both a sample ofyounger females (2129 years) and a sample of olderfemales (6781 years). The following observations areconsistent with summary data given in the article:YF: 29, 34, 33, 27, 28, 32, 31, 34, 32, 27OF: 18, 15, 23, 13, 12Does the data suggest that true average maximum leanangle for older females is more than 10 degrees smallerthan it is for younger females? State and test the relevanthypotheses at significance level .10.
