To determine the # of deer in a game preserve, a game warden catches 415 deer, tags them, and lets them loose.

2075 deer is the estimated #.





M/N=R/C





M=#caught and marked @ time 1


N=#total number in pop


R=# of marked animals at time two


C=total # of individuals @ time 2





Solve for N. THis is the standard mark-recature method for mobile organisms.To determine the # of deer in a game preserve, a game warden catches 415 deer, tags them, and lets them loose.
There needs to be more to this question...





This is the first part of a recapture study. The second part would involve catching X number of deer again, and seeing how many of those were tagged. The assumption is that the animals would be captured, and recaptured, randomly.





How many deer did the warden catch again, and how many of those were tagged?To determine the # of deer in a game preserve, a game warden catches 415 deer, tags them, and lets them loose.
this is a relatively simple problem once you know how to set it up.





you have 415 deer tagged. you wanna know how many deer in total you have. you capture 140 other deer 28 of which are tagged so you set up your paper like this:





415/X = 28/140





Then you solve for X.


(I got that using the above paragraph If you can't figure out how I got that let me know.)


The answer is: 2075 deer
