Solution

The correct option is A 23.2 ft
Average is defined as the sum of all data points divided by the total number of data points.

From the given graph, we can tabulate the height of each tree as:

Thus, the average height

$= \frac{12 + 14 + 23 + 22 + 45}{5}$

$= \frac{116}{5}$

= 23.2 ft

Hence, the average height of the trees is 23.2 feet.
