After two incredibly difficult years of study in the Amazonian rainforest, you have collected enough data on the rare purple-ringed, three-toed tree frog to estimate some simple population parameters. In your first year in the rainforest you estimated the population size as 450 individuals. In the second year, you only estimated a population of 415. Answer the questions below and show your work.
