Question

 Malnutrition and Poverty. R. Reifen et al. studied various nutritional measures of Ethiopian school children and published their findings in the paper "Ethiopian-Born and Native Israeli School Children Have Different Growth Patterns" (Nutrition, Vol. 19 , pp. $427-431$). The study, conducted in Azezo, North West Ethiopia, found that malnutrition is prevalent in primary and secondary school children because of economic poverty. A frequency histogram for the weights, in kilograms (kg), of $60$  randomly selected male Ethiopianborn school children ages $12-15$ years old is as follows.

State whether the distribution is symmetric, right skewed, or left skewed.

The distribution is symmetric.

Step-1 Given Information

The given graph is:

we have to State whether the distribution is symmetric, right skewed, or left skewed.

Step-2 Explanation

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 can be divided into two equal halves, one of which is a mirror image of the other.
