Suppose you are interested in studying regional differences in crime rates.  You take a random sample of 100 cities in the South, and find a mean crime rate of 55 with a sample
variance
of 5.78.  A sample of 100 cities in the North has a mean crime rate of 50 with a sample
variance
of 6.72.

In words, what can you say about the relationship between the two variables in this example?  (That is, is the relationship statistically significant?).
