Question

which three questions are statistical questions? a how many runs did the new york yankees score in their last game? b how many hours of sleep per night do students usually get when they have school the next day? c what are the heart rates of the students in mr. petersons physical education class? d how many letters are in the last names of the students in my 6th grade class? e what is the minimum height requirement for a rollercoaster?

Explanation:

A statistical question has variability in the data used to answer it.

• Option A has a single - definite answer (the runs in the last game), so it's not statistical.
• Option B has variability as different students get different amounts of sleep, so it's statistical.
• Option C has variability as students in the class have different heart - rates, so it's statistical.
• Option D has variability as students in the 6th - grade class have last names with different numbers of letters, so it's statistical.
• Option E has a single, set answer (the minimum height requirement), so it's not statistical.
