Celia is a nurse in a geriatric ward.  She noticed that older persons in her care are having problems sleeping at night.  She decided to introduce non-pharmocologic ways of relaxation, specifically, music therapy, massage therapy and aromatherapy.  The results below show the number of hours of uninterrupted sleep of the older persons after each intervention.
