The second hypothesis is that a group of participants given visual inspection training with a video-based training system and a standard left to right, top to bottom search pattern (similar to reading a book) will perform better than a group of participants given basic paper-based training using the same pattern.
The third hypothesis is that a group of participants given visual inspection training with a video training system and a left to right, right to left, top to bottom search pattern (Group 3) will perform worse than the group given video training using a left to right, top to bottom search pattern (Group 2).
