Basic Math

  • Suppose reaction time for drag racers is know to be on average50 ms with a standard deviation of 10 ms and that reaction time isnormally distributed.
  1. • What is the reaction time that separates the fastest 10% ofracers from the rest?
  2. What is the interval that contains the middle 95% ofracers?
  3. Above what value would you expect to find the slowest 60%?

Can you please explain in detail? plus i know for thisproblem we have to use this formula X= z x standard deviation +mean. Where do i get the z for this problem? i know the mean andStandard deviation but where am i supposed to get theZ?
