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 longest average forearm length?
Group B, because three children in the group have the least forearm length of 11 inches
Group A, because three children in the group have the least forearm length of 11 inches
Group A, because seven children have a forearm length longer than 12 inches
Group B, because two children have a forearm length longer than 12 inches
Group A because seven children have forearm length longer than 12 inches
Step-by-step explanation:
We need to look at Group A and everything after 12 inches. If we look at 13 inches, there is four dots. And if we look at 14 inches, there are three dots. Add then together to get seven children's forearm lengths.
