11.33 Osteoporosis. Osteoporosis is a condition in which the bones become brittle due to loss of minerals. To diagnose os- teoporosis, an elaborate apparatus measures bone mineral den sity (BMD). BMD is usually reported in standardized form The standardization is based on a population of healthy young adults. The World Health Organization (WHO) criterion for osteoporosis is a BMD 2.5 or more standard deviations below the mean for young adults. BMD measurements in a popula- tion of people who are similar in age and sex roughly follow a Normal distribution.? (a) What percent of healthy young adults have osteoporosis by the WHO criterion? (b) Women aged 70 to 79 are, of course, not young adults. The mean BMD in this age is about -2 on the standard scale for young adults. Suppose that the standard deviation is the same as for young adults. What percent of this older population has osteoporosis!

11.33 Osteoporosis. Osteoporosis is a condition in which the
bones become brittle due to loss of minerals. To diagnose os-
teoporosis, an elaborate apparatus measures bone mineral den
sity (BMD). BMD is usually reported in standardized form
The standardization is based on a population of healthy young
adults. The World Health Organization (WHO) criterion for
osteoporosis is a BMD 2.5 or more standard deviations below
the
mean for
young
adults. BMD measurements in a popula-
tion of people who are similar in age and sex roughly follow a
Normal distribution.?
(a) What percent of healthy young adults have osteoporosis
by the WHO criterion?
(b) Women aged 70 to 79 are, of course, not young adults.
The mean BMD in this age is about -2 on the standard
scale for
young adults. Suppose that the standard
deviation is the same as for young adults. What percent
of this older population has osteoporosis!
