4. Let’s assume it is “normal” and follows the empirical rule (68 - 95 – 99.7). • There are 50 states and the District of Columbia, so 51 total values • Using the empirical rule and knowing we have 51 different areas, how many of these areas do you expect to fall within one standard deviation of the mean? 5. Give an example of a state or district that falls within one standard deviation of the mean. 6. Give an example of a state or district that falls between one and two standard deviations of the mean

Using the stem and leaf plot below, and also given the standard deviation is 2.7031 and a mean of 12.156 answer these questions. 

4. Let’s assume it is “normal” and follows the empirical rule (68 - 95 – 99.7).
• There are 50 states and the District of Columbia, so 51 total values
• Using the empirical rule and knowing we have 51 different areas, how many of these areas do you expect to fall within one standard deviation of the mean?
5. Give an example of a state or district that falls within one standard deviation of the mean.
6. Give an example of a state or district that falls between one and two standard deviations of the mean.
7. Are there any states that fall more than two standard deviations from the mean? If so give an example.
