Final answer:
The population is 825 and the sample is 150.
Step-by-step explanation:
The population and the sample in this study are given by option C: The population is 825 and the sample is 150.
The population refers to the entire group of individuals or objects of interest in a study. In this case, the population is the total number of individuals being studied, which is 825.
The sample, on the other hand, is a subset of the population that is selected for observation or analysis. It represents a smaller group that is used to make inferences about the larger population. In this case, the sample size is 150.
