In​ 2007, the mean rate of violent crime​ (per 100,000​ people) for 10 regions in the northeast of a certain country was 312. The standard deviation was 123. 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​ 68% of the​ rates?   Approximately​ 68% of the observations fall within the interval:
