Pineal Gland Study. Dr. Marquez hypothesized that fluoride had a deleterious effect
on the pineal gland, which helps with sleeping. He measured the amount of fluoride in
Americans and compared it to the fluoride level in Europeans, where its use in drinking
water has been banned. He knew from reading the literature that the average fluoride
level in Europeans was 40 parts per million (ppm). He collected a
representative sample of 625 Americans and found that their fluoride level was 60 ppm
with a standard deviation of 250 ppm. What is the value of the z-test statistic?
Archaeologists can determine the diets of ancient civilizations by measuring the ratio of
carbon-13 to carbon-12 in bones found at burial sites. Large amounts of carbon-13 suggest a
diet rich in grasses such as maize, while small amounts suggest a diet based on herbaceous
plants. The article "Climate and Diet in Fremont Prehistory: Economic Variability and
Abandonment of Maize Agriculture in the Great Salt Lake Basin" (J. Coltrain and S.
Leavitt, American Antiquity, 2002:453-485) reports ratios, as a difference from a standard
in units of parts per thousand, for bones from individuals in several age groups. The data are
presented in the following table.

- Foot ulcers are a common problem for people with diabetes. Higher skin temperatures on the foot indicate an increased risk of ulcers. The article "An Intelligent Insole for Diabetic Patients with the Loss of Protective Sensation" (Kimberly Anderson, M.S.
