Group A, because three children in the group have the least forearm length of 9 inches. Group B, Because three children in the group have the least forearm length of 9 inches Group A, Because two children have forearm length longer than 10 inches
What's the question m8?
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?
Well to find the average you find the mean....Do you know how to find the mean?
not on this kidn of problems no
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.
so for the second one would be 10 right
or would it be 11?
11. So what would be your answer
O.O What is this now?
No idea what you were doing there.
I would say your answer is B.
