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.

Explanation:

A scatter - plot is used to show the relationship between two variables. In a positive relationship, as one variable (in this case, height) increases, the other variable (arm span) also increases. Looking at the scatter - plot, as the \(x\) - values (height) increase from left to right, the \(y\) - values (arm span) also increase.

Answer:

Yes, the relationship displayed shows arm span increasing as height increases.
