in the formula, (avg number tagged)/(avg caught) = (total number tagged)/x, what does \x\ represent?\nnumber…

Answer:

B. Estimated population size

Brief Explanations:

This formula is related to the mark - recapture method in biology (a subfield of Natural Science). In the mark - recapture formula (\frac{\text{Number of tagged in sample}}{\text{Size of sample}}=\frac{\text{Total number of tagged in population}}{\text{Estimated population size}}). Here, ((\text{AVG number tagged})/(\text{AVG caught})) is similar to (\frac{\text{Number of tagged in sample}}{\text{Size of sample}}), and ((\text{total number tagged})/X) is similar to (\frac{\text{Total number of tagged in population}}{\text{Estimated population size}}). So (X) represents the estimated population size.
