Students in a Statistics course took a test where the highest score was 100. Most of the students did quite well, with more than half of the students getting As and Bs on the test. Most of the rest of the
students earned Cs, with just a few Ds. Only two students received Fs, but their scores were very
low, in the 30s.
If As are for scores in the 90s, Bs for the 80s, Cs for the 70s, Ds for the 60s, and Fs for scores below
60, what is the shape of the distribution of scores? You may want to draw a quick picture based on
the description above.
