Hey Brent, so I do not understand how come the smallest value in the set can be 8.5 and the largest 4.1? Isn't it the other way around?
Also if the 2a is 9.2 how did you get 5.5 (when you subtract 9.2 from the smallest value in a set, which is 3.7, you don't get 5.5)?
Please, can you clarify?
Thanks a lot
