    If there are 50 pieces of data which range from 0 to 100:
    - with a mean of 60 and Root mean square deviation of 8 show that only 1 piece of data can equal 100
    -with a mean of 60 and Root mean square deviation of 8.2 show that only 2 (or less) pieces of data can equal 100
    -with an Root mean square deviation 4√2 or less show that no pieces of data can equal 100
