Answer:

Arithmetic mean is 6.25

Step-by-step explanation:

We are given with the following data;

     X                     f                    f * X

     6                    4                      24

     4                    2                      8

     8                    5                     40

     3                    1                      3    

                    ∑f = 12        ∑f * X = 75  

Arithmetic Mean =   \frac{\sum fX}{\sum f} = \frac{75}{12} = 6.25
