Stewart Fist reported the results of an experiment investigating the link between cell phone use and tumors in mice. The study exposed one hundred mice to cell phone radiation for two half-hour periods each day over eighteen months. The researchers fitted another hundred mice with the same type of antennas, which never had the power turned on. The tumor rate was twice as high in the exposed group as in the unexposed group.

a) Identify the question, population, and sample.
