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)
4 B = 3 12
3 C = 2 6
1 A = 4 4
3 D = 1 3
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]
