Question

plse help me to solve this

Answer 1

Okay well 1st, you would need to find the average of the ages. So what you would do is add5+14 and divide it by 2 and you would end up getting 9.5. Repeat that for the rest of the ages.

Answer 2

And then Idk if you know, but if you go onto stat, edit, plug in the values of the ages you solved for in L1 and in L2, put the total of the number of cases. The average should be when you Stat, Calc and 2-Vars Stat is 34.5 as the average age.
