The following table lists a portion of U.S. life expectancy (in years) for the 50 states; the entire data set, labeled Life_Expectancy, can be found on the text website.

In a report, use the sample information to:
1. Construct appropriate tables (frequency distribution, relative frequency distribution, etc.) and graphs to summarize life expectancy in the United States. Use 75, 76.5, etc. for the upper limits of the classes for the distributions.
2. Discuss where the data tend to cluster and how the data are spread from the lowest value to the highest value.
3. Comment on the shape of thedistribution.
