You are a public health researcher, who is examining the relationship between secondhand smoke exposure and the development of asthma in children. Group A includes 150 children who live with a smoker, and Group B includes 300 children who live in smoke-free households. After one year, 30 children in Group A developed asthma, while 15 children in Group B developed asthma. Calculate and use the relative risk ratio to explain your research to a group of nursing students in 1-3 sentences.
