I'm not sure if this applies to decimals, but in computer science, to find the length of a string, we do:

(Last number - first number) + 1

I have the answer, which is 11, but the tutorial would not show me how they got the answer. I used what you told me and it  did not give me that answer. Thanks though (:

Hmm...

What if you round and then add 1?

E.g. 83.61 is about 84
and 93.59 is about 94 

so 94 - 84 = 10 and then you add 1, which is 11.

Just a guess :)

It will throw off my other answers, and its an online statistics class so all the answers have to be perfect. I am currently on Interpreting the Standard Deviation :/

Oh ok, too advanced for me, I've only done Standard Deviation a few times in Algebra.
