4) The National Health and Nutrition Examination survey
estimated dietary intake of ten key
nutrients. One of those nutrients was calcium (mg). They found in
all adults 60 years or older a
mean calcium intake of 721 mg with a standard deviation 454 mg.
Assume that these values are
for the population mean and standard deviation for the US
population. Also, assume that the
calcium intake measurements of this random variable have a
population distribution shape that
is skewed to...
