Question

Marine Biologists capture, tag, and release 137 Florida manatees into a protected region. Several months later, of 90 captured manatees, 6 have tags. Estimate the population of Florida manatees in the protected region. Show work

Answer 1

The percentage of tagged manatees in the sample is:
\[\frac{6}{90}\]
Therefore 137 tagged manatees represent approximately 6/90 of the population.
The estimated total population is:\[137\times \frac{90}{6}=?\]

Answer 2

2055?

Answer 3

Sorry I should have said "The fraction of tagged manatees........."
