Problem
Sean has the following data: \[ 488 \quad 493 \quad 495 \quad k \quad 489 \] If the median is 489 , which number could \( k \) be? \[ \underline{488} \quad \underline{726} \]
Solution
Step 1 ：Sort the given data: 488, 489, 493, 495, k
Step 2 ：Since the median is 489, then k <= 489
Step 3 ：The options for k are: \( k=488 \)
