Avoiding an accident while driving can depend on reaction time. Suppose that reaction time, measured from the time the driver rst sees the danger until the driver gets his/her foot on the brake pedal, is approximately symmetric and mound-shaped with mean 1 seconds and standard deviation 0.19 seconds. Use the 68-95-917 rule to answer the following questions. The pictures of the 68-95-99] rule in this le may help with the following questions. What percentage of drivers have a reaction time more than 1.38 seconds? 0/o What percentage of drivers have a reaction time less than 0.81 seconds? What percentage of drivers have a reaction time less than 1.19 seconds? W H
