The animal department wants to estimate baboon population. So they paint 50 baboons with a mark. These baboons were then release
d into the jungle. After two months 300 baboons were caught. Among these baboons 25 were marked. To the nearest whole number what is the best estimate for the baboon population?
Half the number of marked baboons showed up in the sample, so we expect the sample size to be about half of the total population. 300 is half of 600.
___
Many assumptions are involved in such an experiment and analysis. Not the least of which are the assumptions that the marked baboons end up evenly distributed through the population, and that the sample is a fair sample of the entire population.
The complete question is shown in the figure below. As you can see one square units is well shown in the graph. So we can conclude that the distance between two consecutive points is 1 unit. If so, then we can calculate the area of the parallelogram as follows:
