Do you want me to find the 17 data entries? /_^

anonymous · Answer

Do you need a solid 6.5? or could it come out as 6.47 and u round up the rest?

anonymous · Answer

I have 2 sets of digits where I get 6.52 and 6.47, just let me know if you want to know what they are.

6.3055556..$$((\sum_{i=1}^{i=17}X i  ) + 3)/18= ?                                                  $$

anonymous · Answer

you know $$(\sum_{1}^{17} X i )/17 = 6.5    => (\sum_{1}^{17} X i ) = 17*6.5 = 110.5 ; substitute    this \in the previous equation..you will get ur new mean   :D$$
