S = {0, 0, 0, 2, 9, 11, 11, 14, 16, 17}
Qt A
All the values are in ascending order so Median = \(\frac{9+11}{2}\) = 10
Qt B
Mean = \(\frac{Total}{10}\) = \(\frac{80}{10}\) = 8
Qt A > Qt B
Answer A

The numbers are already in ascending order, S = {0, 0, 0, 2, 9, 11, 11, 14, 16, 17}
Col. A: Median = \(\frac{5^{th} + 6^{th}}{2}\) term \(= \frac{9 + 11}{2} = 10\)
Col. B: Mean = \(\frac{(0+ 0 + 0 + 2 + 9 + 11 + 11 + 14 + 16 + 17)}{10} = \frac{80}{10} = 8\)
Hence, option A
