If 50 sacks are in a load, how many sacks should be sampled at minimum?

1. 5

2. 10

3. 15

4. 20

The correct answer is: 10

The correct number of sacks to sample from a load of 50 is based on the principles of statistical sampling in quality assurance. In general, when determining how many items to sample from a population, a common recommendation is to take 10% of the total number. For a load consisting of 50 sacks, 10% would equate to 5 sacks. However, to ensure a more robust analysis and account for variability, it is often recommended to sample a minimum of 10 sacks. Sampling 10 sacks provides a better representation of the entire load, allowing for more reliable assessments of quality and reducing the risk of missing defects that might be present in the entire load. While taking fewer sacks might seem sufficient at first, increasing the sample size to 10 enhances the accuracy of the inspection results and increases confidence in the findings derived from the sample. Thus, sampling 10 sacks is the most appropriate choice given the standard practices in inspection protocols.
