Part of the study consisted of a 50-question survey asking about types of foods consumed. Each question was scored on a scale from one: most unhealthy behavior, to five: most healthy behavior.

A prior survey of patients had found the mean score for the population of patients to be u = 2.9. After careful review of these data, the hospital nutritionist decided that patients could benefit from nutrition education. The current survey was implemented after patients were subjected to this education, and it produced these sample statistics for the 15 patients sampled: x = 3.3 and s = 1.2. We would like to know if the education improved nutrition behavior. The hypotheses to be tested are: Ho : u = 2.9 vs. H: u> 3.3. Ho: H = 2.9 vs. H: x = 3.3.
