Chapter 3, Problem 7BSC(choose chapter or problem)
In Exercises 5–20, find the range, variance, and standard deviation for the given sample data. Include appropriate units (such as “minutes”) in your results. (The same data were used in Section 32 where we found measures of center. Here we find measures of variation.) Then answer the given questions.
Car Crash Test Measurements Listed below are head injury measurements from small cars that were tested in crashes. The measurements are in “hic,” which is a measurement of a standard “head injury criterion.” The data are from Data Set 13 in Appendix B, which is based on data from the National Highway Traffic Safety Administration. The listed values correspond to these cars: Chevrolet Aveo, Honda Civic, Volvo S40, VW Jetta, Hyundai Elantra, Kia Rio, and Kia Spectra. Given that all of the cars are small, does it appear that the head injury measurements are about the same for all small cars?
