As the population ages, there is increasing concern about accident-related injuries to the elderly. an article 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 are consistent with summary data given in the article: yf: 28, 34, 31, 27, 28, 32, 31, 34, 32, 28 of: 18, 14, 21, 13, 12 carry out a test at significance level 0.10 to see whether the population standard deviations for the two age groups are different (normal probability plots support the necessary normality assumption). state the relevant hypothesis. (used σ1 for yf and σ2 for of.)
