<title>Describe Shape</title>
<statement>
<p>Based on the graph, would you consider the "number of hurricanes" distribution to be symmetric, skewed to the right or skewed to the left? Check the Skewness statistic box, does the value agree with your judgement from the graph?</p>
</statement>
<choices randomize="no" multiple-correct="no">
<choice correct="yes">
<statement><p>Skewed to the right</p></statement>
</choice>
<choice correct="no">
<statement><p>Skewed to the left</p></statement>
</choice>
<choice correct="no">
<statement><p>Symmetric</p></statement>
</choice>
</choices>
<hint>
<p>Look at the tails of the distribution. Which side extends further? A positive skewness value indicates right skew, negative indicates left skew, and values near 0 indicate symmetry.</p>
</hint>
<solution>
<p>The distribution appears to be skewed to the right, with a longer tail extending toward the higher values. The skewness statistic should be positive, confirming this visual assessment.</p>
</solution>
