When test scores are low, students often ask the teacher whether he or she is going to "curve" the grades. The hope is that by curving a low score on the test, the students will wind up getting a higher letter grade than might otherwise be expected. The term curving grades, or grading on a curve, comes from the bell curve of the normal distribution. If we assume that scores for a large number of students are distributed normally (as with SAT scores) and we also assume that the class average should be a "C," then a teacher might award grades as listed in the table below.

A	1.5 standard deviations above the mean or higher
B	0.5 to 1.5 standard deviations above the mean
C	within 0.5 standard deviation of the mean
D	0.5 to 1.5 standard deviations below the mean
F	1.5 standard deviations below the mean or lower

Suppose a teacher curved grades using the bell curve as in the table above and the grades were indeed normally distributed. What percent of students would get a grade of "A"? Round your answer as a percentage to one decimal place. % What percent of students would get a grade of "B"? Round your answer as a percentage to one decimal place. Suggestion: To find the percentage of students getting a grade of "B," subtract the percentage of students 0.5 standard deviation or less above the mean from the percentage of students 1.5 standard deviations or less above the mean. %
