The director of the campus-computing center did a study to determine the patterns of student computer usage. He found that 15% of the total student computer hours occurred during the first 5 weeks of the term, 25% during the middle five weeks, and 60% during the last 5 weeks. Would a time-series graph of this data be appropriate? Give a reason for your answer.

No. A time-series graph is not ideal for data collected over periods of longer than a week.
No. A time-series graph is not ideal for fewer than 10 events or categories of data.
Yes. A time-series graph identifies the frequency of events or categories in increasing order of occurrence.
Yes. A time-series graph would show how student usage of the computer lab varies during the term.
Yes. A time-series graph represents data that make up parts of a whole.
