The volume of oxygen consumed (in liters per minute) while a person is at rest and while he or she is exercising (running on a treadmill) was measured for each of 50 subjects. The goal is to determine if the volume of oxygen consumed during aerobic exercise can be estimated from the amount consumed at rest. The results are plotted below.

Accepted Answer

there is a positive association between the volume of oxygen consumed at rest and while running, AND there are outliers in the plot.

Answer

there are outliers in the plot, and therefore we cannot determine an association from this plot.
