Answer:
Note that we need calculate the scores between the mean (
) and the mean plus 3 times the standard deviation. It is 3 times since the distance between the values given (513 and 759) divided by the standard deviation is 3 (
)
So the rule say that 99.7% of data is between 
and 
, as it is a normal distribution half of 99.7% is between 
and 
. Hence 49.85% of people score between 513 and 759.
