What type of error occurs when an inspection process rejects conforming product?

α
β
σ
H sub 0

The correct answer is: α

The correct answer is related to Type I errors, which are also known as α (alpha) errors. In the context of an inspection process, a Type I error occurs when a conforming product is incorrectly rejected, meaning that the product meets quality standards, but the inspection mistakenly identifies it as defective. This type of error can lead to unnecessary costs related to the rejection of good products, such as wasted materials, lost time spent on re-inspection, and potential harm to customer satisfaction if the product is not available when needed. Recognizing the implications of Type I errors is essential in quality management, as it emphasizes the need for careful calibration of acceptance criteria and inspection processes to minimize such errors. The other terms relate to different concepts in statistical hypothesis testing and error types, which do not specifically pertain to the rejection of conforming products. Understanding these distinctions is critical for effectively applying Six Sigma methodologies and ensuring quality control processes are optimized.
