Question

While doing research on a local river, a scientist put tags on 418 rainbow trout. Later, the scientist captured 251 rainbow trout, of which 15 had tags. To the nearest whole number, what is the best estimate for the rainbow trout population?

Answer 1

Answer:

  about 6995

Step-by-step explanation:

The second catch indicates about 15/251 of the fish were tagged. Then the population can be estimated to be 251/15 times the number that were tagged:

  (251/15)(418) ≈ 6995

The population can be estimated to be about 6995 trout.
