Use the following to answer the questions below:

Students in a small statistics course collected data to determine if the length of the forearm could be used to predict the length of the foot (both measured in centimeters). Their data are displayed in the provided table.

Forearm (cm)292827232629.5362930242729.532
Foot (cm)26232423252729282323242631

A scatterplot of the data collected by the students is provided. Does there appear to be a positive or negative association between these two variables? What does this mean for these two variables?

A scatterplot shows the relationship between forearm and foot in centimeters. The horizontal axis is labeled, Forearm (in centimeters) and has markings from 22 to 36 in increments of 2. The vertical axis is labeled, Foot (in centimeters) and has markings from 22 to 31 in increments of 1.The dots are randomly scattered across the graph. The concentration of the dots is more between the points 23 and 30 on the horizontal axis and between the points, 23 and 28 on the vertical axis. The dots are plotted at the following points: (23, 23), (24, 23), (26, 25), (27, 24), (28, 23), (29, 26), (29, 28), (29.5, 26), (29.5, 27), (30, 23), (32, 31), and (36, 29).  All values are approximate.


▸ Positive; This means that people with longer forearms tend to have larger feet.

▸ Negative; This means that people with longer forearms tend to have larger feet.

▸ Positive; This means that people with longer forearms tend to have smaller feet.

▸ Negative; This means that people with longer forearms tend to have smaller feet.
