The nurse is conducting research on the relative risk of acquiring lung cancer as a result of being exposed to secondhand smoke. The nurse is studying two different groups. Group A includes 400 adults who do not smoke but are exposed to secondhand smoke in their home on a daily basis. Group B includes 400 adults who do not smoke and are not exposed to secondhand smoke in their home. Over the course of 10 years, 20 subjects in Group A are diagnosed with lung cancer, whereas only 2 subjects in Group B are diagnosed with lung cancer. Which is the relative risk ratio that would result from this study?
