A teacher informs his psyhcology 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 28 and a standard deviation of 9.2. 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 28.3, but not a 27.33.) The grades are curved according to the following scheme. Find the numerical limits for each letter grade. Letter Scheme Interval
A Top 11%
B Scores above the bottom 68% and below the top 11%
C Scores above the bottom 32% and below the top 32%
D Scores above the bottom 11% and below the top 68% F Bottom 11%
