The dot plots below show the ages of students belonging to two groups of salsa classes: based on visual inspection, which group most likely has a lower mean age of salsa students? explain your answer using two or three sentences. make sure to use facts to support your answer.

That would be Group B 

Because there are a lot of them aged about 7 and none above 21 whereas in Group A there are quite a few aged about 24 and about 28.

I think group b because more of the dots are to the left than in plot a

hope this helps
