Scores on the verbal Graduate Record Exam (GRE) have a mean of
453 and a standard deviation of 122. Scores on the quantitative GRE
have a mean of 651 and a standard deviation of 157. A perfect score
on either exam is 800. Assuming the scores are normally
distributed, what percentage of students score 800 on the
quantitative exam?
The percentage of students that score 800 on the quantitative
exam is approximately _% (Round to the nearest percent as
