Which is an example of a statistical question?

Vikki [24]

Hey there, Damonealy!

The correct answer should be D since you are talking about multiple amount of data. As you can see, question number 1-3 are talking about the age of a single person but question D is talking about the ages of multiple students which can be used in a statistic.

Thank you for using Brainly.
See you soon!
