A materials testing technician measures how the compression of a polymer bumper changes under different compressive loads. The results are recorded in the table below:
| Load (kN) | Compression (mm) |
|---|---|
| 0.0 | 0.0 |
| 5.0 | 1.2 |
| 10.0 | 2.4 |
| 15.0 | 3.6 |
| 20.0 | 4.4 |
| 25.0 | 4.9 |
The technician states:
"The compression of the polymer bumper is directly proportional to the applied load across the entire range of loads tested."
Evaluate the technician's statement. Use data from the table to support your answer.
