As the saying goes, any man should accomplish three things in his life: build a house, plant a tree, and raise a child. Let us concentrate on the second part for now. A certain gardening magazine conducted a survey to determine how many people have planted a tree in their life. The results stated that 13% of the respondents have planted at least one tree. For the margin of error to be 5%, how many people should be surveyed? Round up to the nearest whole number, if necessary. In order to have a margin of error of 5%, people should be surveyed.
