Correct Answer: 5
Description: Exposure is mobile usage while driving, incidence of accidents under consideration is that of: Incidence of exposed (IE)= 300/1000 Incidence of non-exposed (INE) = 300/5000 RR(Relative Risk) = = 5 ( thus mobile usage is associated with 5 times increased incidence of accident)
