Question: Loggers like to use readily available measurements to establish the number of board feet of lumber in a tree. (A board foot of lumber is of a cubic foot, equivalent to a board 12 in. wide, 12 in. long, and 1 in. deep.) Assume the loggers measure tree diameters in inches at (their) waist height.
Develop a model that predicts board feet as a function of diameter in inches. Use the following data for your test:
| x | 17 | 19 | 20 | 23 | 25 | 28 | 32 | 38 | 39 | 41 |
| y | 19 | 25 | 32 | 57 | 71 | 113 | 123 | 252 | 259 | 294 |
The variable x is the diameter of a ponderosa pine in inches and y is the number of board feet divided by 10.
- Consider two separate assumptions, allowing each to lead to a model. Completely analyze each model.
Assumption 1 : All trees are right circular cylinders and all trees are about the same height.
Assumption 2 : All trees are right circular cylinders and the height of a tree is proportional to the diameter.
