Answer 2

Survey of the height of child (below five years of age) of ten well-off and ten poor families in a locality.

Explanation:

There is total of 10 children(below five years of age) in 10 well-off families and 11 children (below five years of age)  in 10 poor families (see 1st Image).  

A Scatter graph is plotted (See 2nd Image). Where the age of children (Year) is taken in the X-axis and Height of children (inches) on the Y-axis. And the Trend line is drawn.

If we look carefully at both graphs, we can see that well-off family children are taller than poor families children.
