The following problem is an example of the capture—recapturemethod of population estimation. A researcher wants to estimate the number of rabbits in a region. The researcher sets some traps and catches 30 rabbits. After the rabbits are tagged, they are released unharmed. A few days later the researcher sets some traps again and this time catches 35 rabbits. Of the 35 rabbits trapped, 5 are tagged, which indicates that they had been trapped a few days earlier. Based on these results, what is the best estimate you can give for the number of rabbits in the region? Solve this problem in three different ways, explaining your reasoning in each case.

Hint: Find the limits on r and s by sketching the area of integration in the (x, y) plane along with the r and s axes, and then show that the same area can be covered by s from 0 to r and r from 0 to 1.arrow_forward
