Questions: A quality control inspector must stare at a fast-moving line of finished products in a manufacturing plant. She must quickly pull out any products that have a defect. Every time she does this, she must stop the line, delaying production. Her effectiveness depends on a high number of just noticeable differences misses limens hits

The answer is the last one: hits.

Explanation for each option:

1. Just noticeable differences: This term refers to the minimum difference in stimulus intensity that a person can detect. It is not directly related to the inspector's task of identifying defective products.
2. Misses: This term refers to instances where the inspector fails to identify a defective product. A high number of misses would indicate poor effectiveness, which is not desirable.
3. Limens: This term is another word for thresholds, specifically the point at which a stimulus is strong enough to be detected. It is not directly relevant to the inspector's task.
4. Hits: This term refers to correctly identifying and pulling out defective products. A high number of hits indicates that the inspector is effective at her job.

Summary: The quality control inspector's effectiveness depends on a high number of hits, which means correctly identifying and removing defective products from the production line.
