Scenario 1:

A researcher is examining the effects of a treatment to stop smoking. The research question is: Is there a relationship between the number of hours spent in a smoking treatment and the number of cigarettes smoked per week? The researcher uses two randomly selected groups of 20 participants each, one that receives the treatment and one that does not. The researcher is examining the average amount of cigarettes the participants smoke per week before and after the treatment. The preliminary results show that both groups were normally distributed.
