The age of a tree can be determined by counting each annual growth ring in the trunk of the tree. A common measure of the size of a tree is the "diameter at breast height" DBH. "Breast height" is defined as 4 ½ feet above the uphill side of the tree. Consider the following data on 12 northern red oaks from southwestern Wisconsin: 93 52 57 75 16.5 11.0 10.5 | 9.0 |6.0 45 28 12 15 1.5 Age(years) | 97 88 81 9.5 11 DBH(inch) | 12.5 12.5 8.0 1.0 1.0 What is the range of validity of this model?
