To determine the rejection rate of Process C, it is essential to understand the calculation involved in finding rejection rates within a manufacturing or processing context. The rejection rate is typically calculated as the number of rejected products divided by the total number of products produced, expressed as a percentage.

In this scenario, if Process C has a rejection rate of 20%, this suggests that out of all the products produced in that process, 20% did not meet quality standards and were subsequently rejected. This percentage indicates the efficiency and effectiveness of the production process in maintaining quality.

The calculation could stem from data indicating that for every 100 units produced, 20 units were rejected, leading directly to the rejection rate of 20%. This metric is critical in industrial and systems engineering as it helps in identifying areas for improvement, reducing waste, and increasing overall operational efficiency within the manufacturing process.

Understanding the rejection rate allows for clearer insights into quality control practices, operational performance, and potential adjustments needed to enhance productivity. A 20% rejection rate serves as a benchmark to compare against other processes or to facilitate targeted improvements.
