Please help me Emily conducted a survey to find out the amount of time high schoolers spend surfing the Internet. From the data collected, the range of time spent was 2 hours. What does this range say about the data?

1. All the students surveyed spend exactly 2 hours surfing the Internet.

2.All the students surveyed spend an average of 2 hours surfing the Internet.

3.The quotient between the greatest amount of time and the least amount of time spent surfing the Internet is 2 hours.

4.The difference between the greatest amount of time and the least amount of time spent surfing the Internet is 2 hours.
