Average trace element concentrations (ug/8) in scalp hair
1. If it were possible to measure the presence of copper in the hair of all males with epilepsy in the
world, do you think the average would be exactly 14 pg/g? Explain your thinking.
2. The journal article that contains the results of the study actually reports that males with epilepsy
have an average of 14 ± 9 µg/g of copper in their scalp hair. What do you think 14 + 9 µg/g
means in this situation?
