Tall Trees
As a biologist, you wish to see if there is a relationship between the heights of tall trees and their diameters. You find the following data for the diameter (in inches) of the tree at 4.5 feet from the ground and the corresponding heights (in feet).
Diameter (in.) | Height (ft) |
1024 950 451 505 761 644 707 586 442 546 |
261 321 219 281 159 83 191 141 232 108 |
