A definition of a statistical question is given below. Statistical question:
Any question whose answer could involve working with more than one data value.
In each situation below, determine whether the question is a statistical question.

First 2 are statistical, because you are asking more than one person, which will result in more than one number(more than one data value)

The other questions are about one person asking one other person about something to get numerical data.
If you only ask 1 person, you will have 1 answer. 1 answer is one data value, but statistical questions must have more than one data value.
