The mean weight of the fish was 4.3875kg
He forgot to make his own record of the weight of the last fish but the first 7 fish were
4.8kg,5.5kg,6.2kg,3.3kg,4.3kg and 4.8+kg

if last or 8th fish is x, then
%284.8%2B5.5%2B6.2%2B3.3%2B4.3%2B+4.8%2Bx%29%2F8=4.3875
%2828.9%2Bx%29%2F8=4.3875
28.9%2Bx=8%2A4.3875
28.9%2Bx=35.1
x=35.1-28.9
x=6.2
the weight of the last fish was 6.2kg

Your post is written EXTREMELY INACCURATELY, so I hardly understand what is written there.

For example, it says 

    " . . . but the first 7 fish were 4.8 kg, 5.5kg, 6.2kg, 3.3kg, 4.3kg and 4.8 kg."

In this list my eyes see only 6 weights, instead of promised 7.

Could you please comment it ?
