Answer:
Option 3
Step-by-step explanation:
Options numbered 1 to 4, top to bottom
Plot the scores in increasing order
20, 24, 25, 27, 29, 31, 34
The first and forth options can be eliminated because the whiskers do not cover the upper end of the range correctly. First ignores 34 and last includes 35, which is not in our score list.
The second option incorrectly places the median score at 25
The third option correctly places the median score at 27, the lower quartile at 24, and the upper quartile at 31
