The median of the following data is:
17, 8, 9, 5, 26, 19, 13, 26, 29

The correct answer is (B) 17.

Step-by-step median computation:

• Given dataset ($n = 9$ observations): $17, 8, 9, 5, 26, 19, 13, 26, 29$.
• Arrange the data in ascending numerical order:
• $5, 8, 9, 13, <strong>17</strong>, 19, 26, 26, 29$.
• For odd $n = 9$, the median is the $\left($$\frac{n + 1}{2}$\right)$\text{th}$ = \left($\frac{9 + 1}{2}$\right)$\text{th}$ = 5$\text{th}$ term.
• The 5th value in the ordered list is 17.
