Scores on the gre (graduate record examination) are normally distributed with a mean of 513 and a standard deviation of 82. use the 68-95-99.7 rule to find the percentage of people taking the test who score between 513 and 759. the percentage of people taking the test who score between 513 and 759 is %

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.
