Answer:
A) It is not a statistical question because the data is a single number.
Step-by-step explanation:
A statistical question is a question that can be answered by collecting data that vary.
What was the high temperature in Chicago yesterday?
This is not statistical as its answer will not vary. It has been specifically asked that what was the HIGH temperature, so its answer will be a single value.
Rather, if it were to be a statistical question, it would have been - What was the temperature in Chicago throughout the day?
So, option A is correct.
