The best prediction of the total number of tagged salmon in a sample of 2000 is 100.
<h3><u>Predictions</u></h3>
To determine what is the best prediction of the total number of tagged salmon in a sample of 2000, the following calculation must be performed:
- 800 = 40
- 2000 = X
- 2000 x 40 / 800 = X
- 80000 / 800 = X
- 100 = X
Therefore, the best prediction of the total number of tagged salmon in a sample of 2000 is 100.
