You are a ranger in a park that has over 10,000 trees. You have been asked to construct a 98% confidence interval for the proportion of the park's trees that are maples, with a margin of error of 0.1. A previously drawn random sample of trees in the park had 75% of the trees as maples. How large of a sample must you take for a margin of error of 0.1? (Round up to the next whole number.) trees
