2. A researcher wishes to determine if there is a relationship between the amount of alcohol a person consumes in a week and the amount of sleep that person gets during the week. There are 200 willing participants that will be randomly selected to one of four treatment groups and the amount of alcohol and average number of hours of sleep for each group will be recorded. Help develop an experiment that this researcher could use which includes a control group, three other treatment groups, a possible confounding variable, and a solution for blocking or controlling that confounding variable.
