Make a bar chart for the average of all the four groups showing the percentages of each fish.

If there are 4528 fish in the large container in the front of the room

How many fish would you predict would be Ghagot based on your sample?

Ans: 4528* 14.46%= 654

How many fish would you predict would be Ghagot based on the average of four groups?

181 Fish in Average.

If your sample contained 1000 litres of water from Hakaluki Haor and the volume of Hakaloki Haor is 125,000,000 cubic meters, how many Ghagot fishes would you expect to find in the whole Haor based on your sampling? Be sure to include your calculations in your answer.

1 Cubic Metre= 1000 Litre
So, 125,000,000 Cubic Metre= 125,000,000,000 Litre
In 1000 Litre 35 Ghagot

So in (125,000,000,000/1000) Litre = 4375000000 Ghagot Approx.
