99.7% of the people taking the GRE test would score between 92 and 980

What is the 68-95-99.7 Rule?

The 68-95-99.7% Rule states that for a normal distribution, about 68% of the values fall within one standard deviation from the mean, 68% of the values fall within two standard deviation from the mean and 99.7% of the values fall within three standard deviation from the mean

Given mean of 536 and a standard deviation of 148. Hence:

99.7% of the values fall within three standard deviation from the mean = 536 ± 3(148) = (92, 980)

99.7% of the people taking the GRE test would score between 92 and 980
