An ecologist was attempting to measure the size of a population of beavers in Yellowstone
National Park. To do this, she captured 65 beavers
and marked them with a microchip. Six weeks
later, she recaptured another 65 and found that
only 10% (1/10) had a microchip. What can she
estimate the population size to be? Defend your
answer (tell me why).
