Question
A teacher informs his computational physics class (of 500+ students) that a test was very difficult, but the
grades would be curved. Scores on the test were normally distributed with a mean of 41 and a standard
deviation of 5.1. The maximum possible score on the test was 100 points. Because of partial credit, scores
were recorded with 1 decimal point accuracy. (Thus, a student could earn a 41.8, but not a 40.57.)
The grades are curved according to the following scheme. Find the numerical limits for each letter grade.
