Answer 1

There are more defects from all other causes than from scratches.

Step-by-step explanation:

To determine if there are more defects from scratches than from all other causes, we need to compare the number of defects due to scratches with the number of defects due to other causes.

Out of 34,641 defective lenses, 5865 were due to scratches.

To find the number of defects from all other causes, we subtract the number of defects due to scratches from the total number of defects.

The number of defects from all other causes is 34,641 - 5865 = 28,776.

Therefore, there are more defects from all other causes than from scratches.
