The university uses a four-point grading system, i. e., A = 4, B = 3, C = 2, D = 1, F = 0. What is the student's grade point average for this semester?
a. 2.27
b. 2.5
c. 2.75

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,

hence,

The average will be:

=

On putting the values, we get
