Final answer:
Without specific data, it's impossible to accurately determine the number of bottling plants with 25 to 31 work stoppages. The question likely refers to a dataset which needs to be reviewed to count the instances within the given range.
Step-by-step explanation:
To determine how many bottling plants had between 25 to 31 work stoppages, we would need to refer to a specific dataset or study that provides this information. Normally, such a question would be based on data from a chart, graph, or table that outlines the number of work stoppages for each bottling plant.
Without access to the specific data, it's impossible to give a correct answer. However, if we assume the question is based on a hypothetical or previously given dataset in a textbook or classroom setting, the student is expected to count the number of instances within the given range (25 to 31 work stoppages) to find the correct answer.
