Answer: D
Step-by-step explanation:
A statistical question is a question where you do not get a straight-to-the-point answer. For example, if someone asks "What is your favorite dessert?" is an example of a non statistical question. And when someone asks "What are the most popular desserts in your family?" is an example of a statistical question.
In other words, "a statistical question is a question that can be answered by collecting data and where there will be a variability in the data." Which means that the conclusion isn't determined by only one answer, but a population.
Hopefully that made sense, if not, I suggest watching a lesson on Khan Academy; I found their lessons extremely helpful!
