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.
In this study, the response variable is
A) the volume of oxygen consumed at rest.
B) the volume of oxygen consumed while running.
C) the volume consumed at rest or while running. It doesn't matter which is
considered the response.
D) the measuring instrument used to measure the volume consumed.



Answer :

The results is  the volume of oxygen consumed at rest.

What is aerobic exercise?

Exercise of a modest to high intensity that largely relies on the aerobic energy-generating mechanism is known as aerobic exercise (also known as cardio). The term "aerobic" relates to the usage of oxygen to sufficiently meet energy demands during exercise and literally means "related to, involving, or requiring free oxygen".

What is volume?

Volume, which is measured in cubic units, is the area in three dimensions that matter occupies or that is encircled by a surface. The cubic meter (m3), a derived volume unit, is the SI unit of measurement.

In this study, the explanatory variable is:

the volume of oxygen consumed at rest.

Option a) is correct.

independent or explanatory variable is determined from x axis of scatterplot.

Therefore, Option a) is correct, the volume of oxygen consumed at rest.
