Explanation:

Sub - question 1: Write a survey question for numerical data

A numerical data survey question should ask for a number. For example, "How many hours do you study per day?" This question expects a numerical answer (like 2, 3.5 etc.).

A categorical data survey question asks for a category. For example, "What is your favorite color?" The answers will be categories like red, blue, green etc.

A statistical question is one that anticipates variability in the data.

• Option a: "What is the typical amount of rainfall for the month of June in the Galapagos Islands?" - There is variability in rainfall amounts over different Junes, so it's statistical.
• Option b: "How much did it rain yesterday at the Mexico City International Airport?" - This is about a single event (yesterday), no variability, not statistical.
• Option c: "Why do you like to listen to music?" - This is a qualitative question about reasons, not statistical (statistical questions are about numerical or categorical data with variability).
• Option d: "How many songs does the class usually listen to each day?" - "Usually" implies looking at multiple days, so there is variability, statistical.
• Option e: "How many songs did you listen to today?" - This is about a single day (today) for an individual, no variability, not statistical.
• Option f: "What is the capital of Canada?" - This is a factual question with a single answer, not statistical.
• Option g: "How long does it typically take for 2nd graders to walk a lap around the track?" - "Typically" implies looking at multiple 2nd graders, so there is variability, statistical.

So the statistical questions are a, d, g.

Answer:

How many hours do you study per day?
