Answer 1

An island has 12 fur seal rookeries (breeding places). To estimate the fur seal pup

population in Rookery A, 5611 fur seal pups were tagged in early August. In late August, a

sample of 1000 pups was observed, and 163 of these were found to have been previously

tagged. Use a proportion to estimate the total number of fur seal pups in Rookery A.

using a proportion

1,000/163=x/5,611

solve for x

x=(1,000/163)*5,611

x=34,423

answer is 34,423 fur seal pups
