The correct answer is: B. Applying the theory’ of probability to sample testing or inspection
Statistical quality control (SQC) is a process used to monitor and control the quality of products or services. It involves the use of statistical methods to collect and analyze data, and to identify and correct defects.
SQC can be applied to a wide range of products and services, including concrete. In the context of concrete, SQC can be used to monitor the quality of the materials used, the mixing process, and the curing process. It can also be used to identify and correct defects in the finished product.
SQC is an important tool for ensuring the quality of concrete. It can help to reduce the risk of failures, and to improve the overall quality of the product.
Here is a brief explanation of each option:
- Option A: Measurement of risks to eliminate failures. This is not the correct answer because SQC is not about measuring risks. It is about monitoring and controlling the quality of products or services.
- Option B: Applying the theory’ of probability to sample testing or inspection. This is the correct answer because SQC does involve the use of statistical methods to collect and analyze data.
- Option C: Reduction in wastage of inspection costs. This is not the correct answer because SQC is not about reducing costs. It is about monitoring and controlling the quality of products or services.
- Option D: Reduction in costs for the removal of defects. This is not the correct answer because SQC is not about reducing costs. It is about monitoring and controlling the quality of products or services.
