what can be interpreted from the range of this graph?
a) the range represents the 24-month time period of the study
b) the range represents the number of users each month for 24 months
c) the range represents the 20-month time period of the study
d) the range represents the number of users each month for 20 months

Explanation:

To determine the correct interpretation of the range from the graph, we analyze the axes:

• The x - axis (horizontal) represents the "Number of Months" with values up to 24.
• The y - axis (vertical) represents the "Number of Users (in thousands)".

The range of a graph (for the dependent variable, which is the number of users here) represents the set of possible values for the dependent variable. Let's analyze each option:

• Option a: The range is about the number of users, not the time period. The time period is on the x - axis, so this is incorrect.
• Option b: The y - axis (range - related for the dependent variable) shows the number of users, and the x - axis goes up to 24 months. So the range (of the number of users) is for the 24 - month study period. This makes sense.
• Option c: The x - axis does not stop at 20 months (it goes to 24), so the study period is not 20 months. Thus, this is incorrect.
• Option d: The range is for the number of users over the 24 - month period (since the x - axis goes to 24), not 20 months. So this is incorrect.

Answer:

b. The range represents the number of users each month for 24 months
