The specification requires 95% compaction. The maximum dry density is 124 pcf and the field dry density is 118 pcf. Based on density alone, how should the lift be judged?

1. It fails because 118 pcf is less than 124 pcf
2. It passes because 118/124 is about 95.2%
3. It fails because 95% compaction means exactly 95.0 pcf
4. It cannot be judged without converting to metric units
