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 1.5 seconds and standard deviation 0.17 seconds. Use the 68-95-99.7 rule to answer the following questions. This web site 68-95-99.7 rule graphically depicts the 68-95-99.7 rule and may help with the following questions. What percentage of drivers have a...
