Question

the equation needed to estimate population size from a population sampling study is: (avg number tagged)/(avg caught) = (total number tagged)/x what does x stand for? the estimated population size the number tagged on the second capture the number caught on the last capture the number caught on the first capture

Explanation:

The formula is based on the mark - recapture method. In the mark - recapture formula \(\frac{\text{Average number tagged}}{\text{Average caught}}=\frac{\text{Total number tagged}}{\text{Estimated population size}}\). By cross - multiplying and solving for the unknown (in this case \(X\)), we can see that \(X\) represents the estimated population size. This is a common formula in population ecology (a sub - field of Biology, which is a Natural Science) to estimate the size of a population.

Answer:

The estimated population size
