Researchers want to estimate the size of two populations ofGalapagos tortoises on two different islands. They do this bymaking two trips to each island. On the first trip to Island A, 50tortoises are captured and marked, and on the second trip, 60tortoises are captured, of which 8 are marked.On the first trip toIsland B, 47 tortoises are captured and marked, and on the secondtrip, 38 are captured, of which 13 are marked. Estimate thepopulation sizes of Galapagos tortoises for these two islands.Round to the nearest whole number (2 pts.).
After 5 years, there are an estimated 386 individuals on IslandA, and 139 individuals on Island B. Assuming geometric growth,which island has a higher growth rate? And what will the populationsize of each island be in another 5 years? Give your answers to 3decimal places (5 pts.).
