Based on the scatterplot, we can estimate that it takes approximately 4.5 years for a Weeping Higan cherry tree to reach 16.5 feet in height. We can make this estimate by finding the point on the scatterplot where the average growth rate intersects the height of 16.5 feet and then looking at the corresponding time on the horizontal axis.
