Answer:
Option c (2.27) is the right option.
Step-by-step explanation:
As per the question, the values are:
Credit hours                    Grade                 fiXi
    (fi)                          (Xi)               Â
    4                          B = 3                  12
    3                          C = 2                  6
    1                          A = 4                  4
    3                          D = 1                   3   Â
Now,
[tex]\Sigma fi= 25[/tex]
[tex]\Sigma fiXi = 25[/tex]
hence,
The average will be:
= [tex]\frac{\Sigma fiXi}{\Sigma fi}[/tex]
On putting the values, we get
= [tex]\frac{25}{11}[/tex]
= [tex]2.27[/tex] Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
