What's the question m8?

OpenStudy (anonymous):

The two dot plots below compare the forearm lengths of two groups of schoolchildren: Based on visual inspection of the dot plots, which group appears to have the longer average forearm length?

undeadknight26 (undeadknight26):

Well to find the average you find the mean....Do you know how to find the mean?

OpenStudy (anonymous):

not on this kidn of problems no

undeadknight26 (undeadknight26):

Well let me show you how for the first one and you can do it for the second one: 9,9,9,10,10,10,10,10, 11, 11 = 99 / 10 So the average/mean is 9.9 for the first set.

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

so for the second one would be 10 right

OpenStudy (anonymous):

or would it be 11?

undeadknight26 (undeadknight26):

11. So what would be your answer

OpenStudy (anonymous):

11/10

undeadknight26 (undeadknight26):
