Find the approximate mean (rounded to the nearest integer), mode and median of the messages received on 7 consecutive days: 7, 13, 5, 9, 6, 5, 10.
Answer: C. 8,5,7 — Correct calculations: Mean: Sum the values: 7 + 13 + 5 + 9 + 6 + 5 + 10 = 55. Mean = 55/7 = 7.857, which rounds to 8. Mode: The value 5 appears twice; all…

Show answer & explanation
Correct answer: C
Correct calculations:
Mean:
Sum the values: 7 + 13 + 5 + 9 + 6 + 5 + 10 = 55.
Mean = 55/7 = 7.857, which rounds to 8.
Mode:
The value 5 appears twice; all other values appear once. Therefore, mode = 5.
Median:
Sorted data: 5, 5, 6, 7, 9, 10, 13. With seven values, the middle (4th) value is 7, so median = 7.
Final answer: approximate mean = 8, mode = 5, median = 7. Therefore, option C is correct.
