**Question:** Decide whether the graph represents a discrete random variable or a continuous random variable. **Graph**: The graph displays a number line ranging from 0 to 20, with a line segment marked along the number line. The segment starts at a point just above 0 and extends to just above 20. It shows the range of "The length of time students use a computer each week." **Options:** - Does the graph represent a discrete or continuous random variable? Choose the correct answer below. 1. ○ The length of time is a random variable that is countable, so it is a discrete. 2. ○ Continuous, because the length of time is a random variable that is uncountable. **Additional Information:** The time remaining for this question is 00:55:39, as indicated by a timer on the screen. **Navigation:** - A "Next" button is present to proceed to the next question.
