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.)

Expert Solution

Step 1

In question,

Given that the mean rate of the violent crime for 10 regions in the northeast of a certain country was 322 and the standard deviation was 112 and distribution of the violent crime is unimodal and symmetric. Then We'll find that between what values would we expect to find 68% of the rates using empirical rule.

The solution is below,
