A.
7

B.
8.5

C.
9.5

D.
10

Respuesta :

The answer is B) 8.5

To find the mean add up all the numbers then divide it by the amount of numbers, it asks whats the mean of the calls received so we can ignore the Days.

So all the numbers add up to 68, and there is 8 numbers. 

68 ÷ 8 = 8.5

Hope this helped.
