Quizplus · Accepted Answer

The relative risk is a ratio of the probability of an event occurring in an exposed group versus a non-exposed group. In this context, "always exceeding the speed limit" is the event, and "people under 30" versus "people over 30" are the exposed and non-exposed groups, respectively. A relative risk of 2.5 means that people under 30 are 2.5 times more likely to always exceed the speed limit compared to people over 30.
