Answer:
"What is the typical number of holes for the buttons in the jar" Is the choice that satisfies the question.
Explanation:
A statistical question is one that represents an average of the whole. "are there any square buttons in the jar" would return a boolean, or binary response of yes or no, and "How many buttons are in the jar" Would have to do with the whole of the buttons, but there's no differentiation between one button and the next.
