The Glen arboretum wants to start removing invasive Norway Maple trees. To determine just how bad the problem is you set up five plots that are three meters on each side. You find that your plots have 2, 5, 9, 1, and 3 Norway Maples.
a. What is the density of Norway Maple trees in the Glen Arboretum per hectare?
b. How many Norway Maples should we expect to remove from the 10 area Glen Arboretum?
