Answer to Question 1

Year A B C D F Total
Freshman 6.5 8.5 14.0 4.0 1.5 34.5
Sophomore 7.0 11.5 8.5 5.0 0.5 32.5
Junior 8.5 9.5 5.0 1.0 0.5 24.5
Senior 2.5 4.0 2.0 0.0 0.0 8.5
Total 24.5 33.5 29.5 10 2.5 100

The percentages of students failing the class for freshmen, sophomores, juniors, and seniors are 1.5, 0.5, 0.5 and 0.0, respectively. It appears that the earlier a student is in his or her college career, the worse they will do in class.
