Describe the shape of the data distribution.

Symmetric

Step-by-step explanation:

For a box plot , a symmetric data set displays the median in the middle of the box.

Also, We know that a distribution is said to be skewed if it has longer whisker at one side than the other.

But in the given box plot , the median looks at the middle of the box.

Therefore, the given box-plot describes a symmetric distribution.

so mark-up is 0.4 multiplied by 180 = 72
