there are 10 marked whales

Question

there are 89 whales counted
and 8 marked whales counted
what would be the best estimate for the population

Answer 1

The best estimate for the population would be 89 divided by the proportion of marked whales, which is 8 out of 10.

89 / (8/10) = 111.25

Therefore, the best estimate for the population would be approximately 111 whales.
