dendrologist (tree scientist) wants to determine the abundance of a particular disease in a forest with mahogany trees, ficus trees, fig trees, wimba trees, and lupuna trees. The dendrologist estimates that the forest contains about 5000 trees from each species, but only fig trees are affected by the disease. He decides to sample 900 fig trees to determine disease prevalence. In order to obtain a confidence level of 95% with no more than a 3% margin of error, the dendrologist would need a sample of at least _[blank A]_ fig trees. Based on the information given in the problem, we can conclude that he _[blank B]_ a large enough sample to obtain the desired confidence level and margin of error.
