The age of a tree can be determined by counting each annual growth ring in the trunk of thetree. A common measure of the size of a tree is the "diameter at breast height" DBH. "Breastheight" is defined as 4 ½ feet above the uphill side of the tree. Consider the following data on12 northern red oaks from southwestern Wisconsin:1115281.5 1.06.045125216.5 11.0 | 10.5 9.0Age(years) | 9793888175571.0DBH(inch) | 12.5 12.5 8.0 9.5d)What is the range of validity of this model?
