Divide the sum of 8, 6, 7, 2, 0, 4, 7, 2, 3, by their mean
A
9
B
8
C
7
D
6
correct option: a
Sum = 8 + 6 + 7 + 2 + 0 + 4 + 7 + 2 + 3 = 39
mean = \(\frac{39}{9}\) = 4.33
then \(\frac{sum}{mean}\) = \(\frac{39}{4.33}\)
= 9
mean = \(\frac{39}{9}\) = 4.33
then \(\frac{sum}{mean}\) = \(\frac{39}{4.33}\)
= 9
