A person’s lean body mass measures how much non-fat mass a person has. This includes bones, muscles and organs. A person’s metabolic rate is how
much energy a body burns while at rest. Below are the body mass and
metabolic rates for 12 people.

c. Use the scatter plot and the correlation coefficient to explain if there is a
correlation between body mass and metabolic rate.
