Question

The reaction time of a driver to visual stimulus is normally distributed with a mean of 0.4 second and a standard deviation of 0.05 second.

  • What is the probability that a reaction requires more than 0.5 second?
  • What is the probability that a reaction requires between 0.4 and 0.5 second?
  • What is the reaction time that is exceeded 90% of the time?

 

Summary: This question belongs to mathematics and discusses about probability operations.
