Question: Crime data study - states

This week, we studied how to compare data for both dependent and independent samples. For this case study, you are going to play two roles. First, you will be a statistician and perform a comparison of the data. Then you will play the role of “The Media” and report whether one state is “more dangerous” than the other for one particular crime.

Your Assignment – data calculation

On the course website, you can find the data for seven crimes for both Ohio and Michigan for each year from 1960 and 2000. With this data, you are to do the following:

1. Use Robbery Data for both States

2. Using the Robbery data for both states, construct a confidence interval for two dependant population means and perform the calculations to determine the true difference in the per capita crime rate. Use a 95% confidence interval. Determine which state has a greater danger of robbery occurring.
