A graph has height (inches) on the x-axis and arm span (inches) on the y-axis. Points are at (30, 27), (45, 45), (53, 50), (60, 60), (67, 70), and (73, 72).

Question

Identify if there is a relationship between the variables.
No, there is no relationship because the points are all up and down.
Yes, the relationship displayed shows arm span increasing as height increases.
Yes, the relationship displayed shows arm span decreasing as height increases.

Answer 1

The relationship displayed shows arm span increasing as height increases.

To elaborate, the points you provided indicate a trend where, as the height (inches) increases on the x-axis, the arm span (inches) on the y-axis also tends to increase. The points generally follow a pattern that suggests a positive correlation between height and arm span.
