In 2007, the mean rate of violent crime (per 100,000 people) for 10 regions in the northeast of a certain country was 322. The standard deviation was 112. Assume that the distribution of violent crime rates is unimodal and symmetric. Complete parts (a) through (d) below. a. Using the Empirical Rule, between what two values would you expect to find about 95% of the rates? Approximately 95% of the observations fall within the interval (98, 546). (Type whole numbers.) b. 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 (Type whole numbers.)
