Short Answer

Expert verified

The distribution is right-skewed.

Step by step solution

01

Given Information

To determine whether the given graph is symmetric, right-skewed, or left-skewed.

02

Explanation

Consider the given graph:

If the shape of any distribution is divided into two parts, one of which is the mirror image of the other, the distribution is said to be symmetric.

The graph in question cannot be divided into two equal halves, one of which is a mirror image of the other.

As a result, the graph's shape is asymmetric.

The long tail of the distribution lies towards the higher values of the variate, as seen in the given figure , and the mean is greater than the median.
