1. **Stating the problem:** We are comparing two dot plots representing sprint times (in seconds) for the U.S. qualifier and the Olympic final. Lower times mean faster sprints. 2. **Understanding the data:** The U.S. qualifier times range roughly from 10.9 to 11.15 seconds, while the Olympic final times range from about 10.7 to 11.05 seconds. 3. **Analyzing option A:** "The times in the Olympic final were faster on average than the top 8 U.S. qualifier times." Since the Olympic final times are generally lower (faster) than the U.S. qualifier times, this is likely true. 4. **Analyzing option B:** "All of the times in the Olympic final were faster than all of the top 8 U.S. qualifier times." The Olympic final times start at 10.7 seconds and go up to 11.05 seconds, while the U.S. qualifier times go from 10.9 to 11.15 seconds. Since 11.05 (Olympic max) is less than 11.15 (U.S. max), but 10.9 (U.S. min) is greater than 10.7 (Olympic min), all Olympic times are faster than all U.S. times. So this is true. 5. **Analyzing option C:** "The Olympic final times varied noticeably more than the times of the top 8 U.S. qualifiers." The Olympic final times range about 0.35 seconds (10.7 to 11.05), and the U.S. qualifier times range about 0.25 seconds (10.9 to 11.15). The Olympic final times have a slightly larger spread, so this is true. 6. **Analyzing option D:** "None of the above." Since A, B, and C are true, D is false. **Final answers:** A, B, and C are correct.
