Capture-Recapture: Estimating Populations 10 n = 3 24 240 = 3n 80 = n 30 n = 8 40 1200 = 8n 150 = n 18 n = 2 5 90 = 2n 45 = n 12 n = 6 24 288 = 6n 48 = n The estimate is likely to be too high. 5.A park has a population of ducks. 20 of the ducks are marked with tags. A week later, 24 ducks are caught. 5 of these ducks have tags on.

Capture/Recapture 1. Suppose that naturalists catch, tag, and release 50 deer in a forest. After allowing time for the tagged deer to mix with the others, they catch a sample of 100 deer, 10 of which have tags. What is the estimate for the number of deer in the forest? 2. Suppose that wildlife workers capture 328 penguins on an island, mark them,
