Question

I want to estimate the population of dolphins in Ingall Bay. I capture and tag 20 dolphins before releasing them. I then capture 56 dolphins and 7 have tags. Estimate how many dolphins are in the bay

Answer 1

160

Explanation:

Based on your information, you can use the mark and recapture method to estimate the population of dolphins in Ingall Bay. The formula to estimate the population size is:

(N1 x N2) / M

where N1 is the number of dolphins tagged in the first capture,

N2 is the total number of dolphins captured in the second capture,

and M is the number of tagged dolphins recaptured in the second capture.

Substituting the given values, we have:

(20 x 56) / 7 = 160

Therefore, the estimated population of dolphins in Ingall Bay is approximately 160.
