Question 414203
To estimate the population of dolphins in a region, biologists capture and tag 200 dolphins, then release them. Later, they recapture 60 dolphins and find that of those captured, 4 are tagged.
a. Write an equations of ratios to solve for T, the total estimated population of dolphins.
----
(population count)/(# caught and tagged)=(# caught including tagged)/(#tagged)
(pop ct.)/200 = (60/4)
----
b. What is the estimated population of dolphins in this region? 
(pop ct.) = 200(60/4)
(pop ct.) = 3000
