What is the sample in the study?
The sample in the study is the 90 bottles of ketchup that were randomly selected from the population of bottles produced in the plant on July 16.
C. All bottles of ketchup produced in the plant on July 16.
To answer this question, we need to understand what the term "population" refers to in the context of the study. In statistics, a population refers to the entire group of individuals or items that the researcher wants to make inferences about.
In this case, the quality-control manager randomly selects 90 bottles of ketchup that were filled on July 16. The key information here is that these 90 bottles were selected from a larger group of bottles produced in the plant.
Option A suggests that the population consists of only the 90 bottles of ketchup selected in the plant. However, this would be a limited population that does not represent the entire group of bottles produced.
Option B suggests that the population consists of the 90 bottles of ketchup selected in the plant on July 16. This is a more specific population, but it still does not include all bottles produced in the plant.
Option C suggests that the population consists of all bottles of ketchup produced in the plant on July 16. This is a wider scope and includes all the bottles produced on that specific day.
Option D suggests that the population consists of all bottles of ketchup produced in the plant in the given year. This is the broadest option, as it includes all the bottles produced throughout the entire year.
Based on the information provided, the correct answer would be option C. The population in the study is all bottles of ketchup produced in the plant on July 16.
