An experiment is to be conducted using environmentally safe peppermint oil to study the effectiveness of deterring mice from infesting dwellings. In one dwelling, the peppermint oil will be dispersed via essential oil diffuser; in the other dwelling it will be placed on areas where mice could enter the dwelling. The
researchers will determine the adverse reactions of the mice to the peppermint oil by counting the number of mice in each dwelling after one week. There are
20 mice available for the experiment, and the researchers will use 10 mice for each dwelling. For this experiment, identify the treatments, experimental unit, and response variable.
