It is possible to prove the Iceman's death and last journey?
Yes
No
They are still working to find answers.
His death will never be proved true, just supported.
To find the MEAN of a data set you must find the sum of the numbers, then (a) by the amount of numbers in the data set.
To put a data set in order then find the middle will give you the (a) .
