The given data represented by the graph are:
4 , 5 , 5 , 5 , 5 , 6 , 6 , 6 , 7 , 7 , 10
the mean = ( the sum of the date ) divided by the number of the data
So, the sum of the data =
4 + 5 + 5 + 5 + 5 + 6 + 6 + 6 + 7 + 7 + 10 = 66
the number of the data = 11
So,
[tex]\text{Mean}=\frac{66}{11}=6[/tex]
so, the answer is
