Question
In the capture-recapture method, if C1 is the number caught and marked first, C2 is the number caught the second time, and R is the number of marked animals in the second catch, what is the formula for estimating population size?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The population size is estimated using the Lincoln index: (Number marked in first sample * Total in second sample) / (Number of marked recaptures in second sample) = (C1 * C2) / R.
Hint
The total population is estimated by multiplying the two catch numbers and dividing by the number of marked ones in the second catch.
