For this one, you will have to compute the mean of each set of 3 numbers and see which sets have exactly two decimal places (or none or 1 as we can add a 0 onto it eg. 1=1.00)
I will do A for you and let you do the others.
mean of A=
=
So that one is NOT one of the number sets the work.
Try the rest out and let me know if you have any problems:)
