Scores on the GRE (Graduate Record Examination) are normally distributed with a mean of 513 and a standard deviation of 82. Use

Trava [24]

Answer:

Note that we need calculate the scores between the mean ( $\mu=513$ ) 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 ( $\frac{759-513}{82}=3$ )

So the rule say that 99.7% of data is between $\mu - 3\sigma$ and $\mu + 3\sigma$ , as it is a normal distribution half of 99.7% is between $\mu$ and $\mu+3\sigma$ . Hence 49.85% of people score between 513 and 759.
