Imagine that you are in charge of a program on a college campus that assists students who need help dealing with stress. One of your most important goals is to reduce reported stress levels (as measured on a scale of 1-10), so that by the end of your one-year intervention, students report, on average, stress levels that are 3 points lower than comparative student stress levels from national data. Identify a statistical test that you would use to compare the average reported stress levels of the students to national data, and how you would know if the average stress level of students in your sample shows a statistically significant difference from the average stress level in the national data.
