New parents were just told by their physician that their son is two standard deviations above the mean. The parents later asked the nurse what that means. The nurse will explain by stating,
 
  A)
  If your child is one standard deviation from the norm that translates to mean, he will be taller than 50 of his peers.
  B)
  This is great news since it means you will have a larger baby than most.
  C)
  Being two standard deviations above the mean translates into that your child will likely be taller than 95 of children in the population.
  D)
  With the mean being average at 50, two standard deviations means that your child will be at least 99.7 taller than his brother.

Ans:
C

Feedback:

The standard deviation determines how far a value varies or deviates from the mean. The points one standard deviation above or below the mean should include 68 of all values and two standard deviations 95 of all values. If a child's height is within one standard deviation of the mean, he is as tall as 68 of children in the population.
