**Possible Answers:**

Insufficient information is given to answer the question.

**Correct answer:**

Insufficient information is given to answer the question.

Explanation:

A box-and-whisker plot gives the lowest and highest scores and the three quartiles (including the median), which depend on the *relative position* of the scores. The standard deviation of the scores depends on the *scores themselves*, which are not reflected in the diagram. The question cannot be answered from the box-and-whisker plot.
