Final answer:
The upgrade in the production machinery represents an increase in data volume. The upgraded machinery captures data about the fit tolerance for assembled parts of each unit produced, resulting in a larger volume of data being collected and analyzed.
Step-by-step explanation:
The upgrade in the production machinery represents an increase in data volume.
Before the upgrade, inspectors sampled 10 percent of units produced to gather data. This means that a smaller proportion of units were being analyzed. However, with the upgraded machinery, data about the fit tolerance for assembled parts of each unit produced is captured. This results in a larger volume of data being collected and analyzed.
