The World Health Organization (WHO) criterion for osteoporosis is a BMD 2.5 standard deviations below the mean for young adults. BMD measurements in a population of people similar in age and sex roughly follow a Normal distribution. The % of healthy young adults have osteoporosis by the WHO criterion is .62. Mean BMD for women ages 70-79 is about 2 standard deviations below the mean for young adults. Suppose that the standard deviation for these older women is the same as for young adults. What percent of this older population have osteoporosis (that is, BMD at least 2.5 standard deviations below that of young adults)?
