A conservation team monitors a wild ungulate population using capture-recapture. In Phase 1, they capture and tag 120 animals. In Phase 2 (after 3 months), they capture 180 animals and find 36 with tags.

Using the Lincoln-Petersen estimator N^=n1×n2m\hat{N} = \frac{n_1 \times n_2}{m}, the estimated population size is approximately 600 animals.
