relationship between geographic location and depression. A sample of 60 individuals,

20 were residents of New York, and 20 were residents of North Carolina. Each of the
individuals sampled was given a standardized test to measure depression. The data
collected follow; higher test scores indicate higher levels of depression. These data
are contained in the file Medical1.
