I need help checking if my answers are correct.

For the following assignment:

a) Identify the question, population, and sample.

question: Does cell phone usage time correlate with tumor growth?

population: mice

sample: 200 mice

b) Discuss any potential bias or lurking variables that may affect the results.

Tumor growth can be caused by factors other than cell phone usage.

c) Write about the extent to which we can generalize the findings to all people who use cell phones.

From the information given about the sample, only a general statement can be made. This is because we do not want to generalize for any unknown or missing characteristics.

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.
