Question

Decide whether each situation demonstrates a discrete or continuous random variable.

1. The number of faculty members who entered Lindner before 9:00 AM today.  ---Select--- Discrete Continuous both Continuous and Discrete neither Continuous nor Discrete
2. Your weight in kilograms every morning ---Select--- Discrete Continuous both Continuous and Discrete neither Continuous nor Discrete
3. The total distance in miles to the airport for all of the students attending BANA2081 on any given day.  ---Select--- Discrete Continuous both Continuous and Discrete neither Continuous nor Discrete
4. The number of students in this room on any given day at noon.  ---Select--- Discrete Continuous both Continuous and Discrete neither Continuous nor Discrete
5. The amount of time yesterday each student studied for this exam.

Answer 1

1) This is Discrete random variable because it's says 'number of faculty members' which is countable and finite.

2) This is Continuous random variable because it's about weight which can take infinite values between two integers.

3) This is Continuous random variable because it's about distance which can take infinite values between two integers.

4) This is Discrete random variable because it's says 'number of students' which is countable and finite.

5) This is Continuous random variable because it's about time which can take infinite values between two integers.

Please comment if any doubt. Thank you.
