In 2007, the mean rate of violent crime (per 100,000 people) for 10 regions in the northeast of a certain country was 350. The standard deviation was 127. Assume that the distribution of violent crime rates is unimodal and symmetric. Using the Empirical Rule, between what two values would you expect to find about 95% of the rates? Using the Empirical Rule, between what two values would you expect to find about 68% of the rates?
