MHB Probability distribution: Estimate the size of the fox population

AI Thread Summary
To estimate the fox population in the park, the method used involves the proportion of tagged to total sightings. With 200 tagged foxes and 14 tagged in 100 sightings, the calculation yields an estimated population of approximately 1,429 foxes. This estimation is supported by the reasoning that 200 represents about 14% of the total population. The calculations and reasoning align, confirming the accuracy of the estimate. The discussion concludes with a consensus on the estimation method used.

In a park , 200 foxes are tagged. In 100 sighting, 14 were tagged. Estimate the size of the fox population ?

This is how approached .

200 tagged : Population 14 tagged : 100
(200x100/14)= Estimated Population = 1,429

I wonder if this is right !

I get the same number. I would use the reasoning that approximately 14% of the total population was tagged, and 200 is 14% of about 1429 (rounded to the nearest integer). :)
 
Thx
 

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
