The average score of the student is 71

Step-by-step explanation:

Given test scores are:

70,54,73,67

And 76 will be counted four times, it has weight 4 while other values are weighted as only 1 each

Hence total number of items will be 4+4 = 8

so,

[tex]Mean=\frac{70+54+73+67+4(76)}{8}\\=\frac{264+304}{8}\\=\frac{568}{8}\\=71[/tex]

The average score of the student is 71
