A study published in the American Journal of Public Health was conducted to determine whether the use of seat belts in motor vehicles depends on ethnic status in San Diego County. A sample of 792 children treated for injuries sustained from motor vehicle accidents was obtained, and each child was classified according to (1) ethnic status (Hispanic or non-Hispanic) and (2) seat belt usage (worn or not worn) during the accident. The number of children in each category is given in the table below.
Ethnicity
Seat belt worn | Hispanic | Non-Hispanic | Total |
Yes | 30 | 149 | 179 |
No | 280 | 333 | 613 |
Total | 310 | 482 | 792 |
