Chapter 3.1, Problem 13E

To determine

To find: Whether the correlation between the two variables is $r>0\text{ or }r<0$ or is closer to $r=0\text{ or }r\pm 1$

Explanation of Solution

Given:

The figure is:

  

The scatter plot is used to depict the relationship that lies between two variables. It shows the correlation’s level in two variables which are known as dependent and independent variable

The relationship between the variables is said to have the perfect positive if the data points in scatter plot form a linear pattern with a positive slope.

In the given figure, data points are following the linear positive pattern which implies that the correlation is greater than 0 and closer to 1, that is, $r>0\text{ and closer to 1}\text{.}$
