Case Study Two

Per Capita Murder Rate for U.S. in 2008

This week, we studied the Central Limit Theorem and Confidence Levels. We are going to apply these lessons to the Case Study for this week.

You can find on the course website a file containing the Crime Data for the United States for 2008. You can also find this data on the FBI website at: http://www.fbi.gov/ucr/cius2008/data/table_05.html

The data in broken down by state in many different categories, but you are going to need only certain, specific values from the table in order to do this case study.

Your Assignment – data collection

For this assignment, you are to randomly select 30 of the states. You are to then construct a 95% confidence interval for the "murder rate and non-negligent manslaughter" per capita using the 30 states you chose.

(This would be the value for the "rate per 100,000 inhabitants" located on the table, one for each state)

In doing your calculations, you are to neatly list all the states you chose with the appropriate corresponding per capita murder rate and show all applicable calculations in the construction of the 95% confidence interval. While Excel is the easiest method to do the organization and calculation of the values, you can also do them by hand as long as the work is neatly presented.

Then, once you have computed the 95% confidence interval for the data, find the FBI’s per capita murder rate for the entire United States for 2008. Compare that value with the 95% confidence interval you calculated and determine if it falls in the interval.

Your Assignment – reporting your findings

When all calculations and comparisons from the previous section are complete, you are to report your findings in a three-paragraph summary. This summary should not detail your method of calculations, rather it should report and interpret your calculations and what they mean.
