Statistical Comparison of Manual and Automatic Sampling at Enterprises

The presented article deals with a detailed analysis of the state of the issue. It is about the characteristics of the organization and the description of its current state, as well as the description, procedure, and comparison of the sampling process in organizations. Next, the specific problems of the process are defined, and in connection with them, a new sampling system is designed, which is fully automated. The article is more specifically focused on statistically significant differences between manual and automatic sampling of business commodities such as coal ore, concentrate, and pellets, which are then submitted for comparison. Sample tests are necessary to make a comparison. The test results are subsequently recorded in the sample test reports. Both manual and automated samples are analyzed using statistical tests to determine if there are statistically significant differences between the data. Such tests were also done in organizations.
