A study of auto safety determined the number of driver deaths per million vehicle sales for the model years 1995 1999, classified by type of vehicle. The data below are for 6 midsize models and 6 SUVs.

Wondering if there is evidence that drivers of SUVs are safer, we hope to create a 95% confidence interval for the difference in driver death rates for the two types of vehicles.
