Hugo recorded the height of each plant after he exposed each plant to a set amount of sunlight daily. The scatterplot shows his results after 2 weeks of exposing each plant to a set amount of sunlight. A graph titled Plant Growth has hours of sunlight on the x-axis and height of plant (inches) on the y-axis. Points are grouped closely together and increase. Point (12, 2) is below the cluster.

Which statement about the outlier in the data set is true?

Hugo should include the outlier because it shows there is no relationship between hours of sunlight and plant height.
Hugo should not include the outlier because it strengthens the effect of showing that sunlight helps plants grow.
Hugo should include the outlier because it shows there is a relationship between hours of sunlight and the height of the plant.
