When can a question be called a statistical question?

No, see solution.

Statistical Question

A question for which we do not expect to get a single answer but rather a variety of answers

In other words, when we ask this type of question, we want to know what the distribution or tendency of answers is. Now let's take a look at the given question.

How many minutes are in your lunch period?

How to Change This Question So That It Is statistical?
