Question

The dean of a local college needs to drop one course from the art program. She decides to pick the course with the lowest average enrollment rate from the previous four semesters. The enrollments of three courses she is considering are: Photography 30, 20, 12, 22; Film Editing 11, 29, 27, 29; Abstract Art 18, 22, 21, 24. Which class has the lowest mean enrollment over the past four semesters

Answer 1

Photography has the lowest mean.

Explanation:

Photography Film Editing Abstract Art

30 11 18

20 29 22

12 27 21

22 29 24

Total 84 96 85

Mean = Sum of all / 4

Photography mean = 84 / 4 = 21

Film Editing mean = 96 /4 = 24

Abstract art mean = 85 / 4 = 21.25

So,

Photography has the lowest mean.
