Final answer:
The population in this scenario is the set of one-ton containers of cattle feed, with a size of 10. The sample is the five-gallon bucket of feed removed from each of the 10 containers, with a size of 10.
Step-by-step explanation:
In this scenario, the population refers to the entire set of one-ton containers of cattle feed. There are 10 one-ton containers, so the population size is 10.
The sample, on the other hand, is the five-gallon bucket of feed removed from each of the 10 one-ton containers. There are 10 buckets in the sample.
