Avoiding an accident while driving can depend on reaction time. Suppose that reaction time, measured from the time the driver first sees the danger until the driver gets his/her foot on the brake pedal, is approximately symmetric and mound-shaped with mean 1.9 seconds and standard deviation 0.12seconds. Use the 68-95-99.7 rule to answer the following questions. What percentage of drivers have a reaction time more than 2.14 seconds?%What percentage of drivers have a reaction time less than 1.78 seconds?%What percentage of drivers have a reaction time less than 2.02 seconds?%
