Dr. Castillejo feels that the maximum pulse rate during the run is a good predictor in explaining the oxygen  consumption in the blood stream. He asserts that if the pulse rate at the end of the run increased, then the  oxygen consumption will also increase, hence his/her heart is functioning well. Based on the R commander output below, check if the data on oxygen consumption and maximum pulse rate (from 152 bpm to 196 bpm) support Dr. Castillejo’s assertion.

Dr. Castillejo feels that the maximum pulse rate during the run is a good predictor in explaining the oxygen 
consumption in the blood stream. He asserts that if the pulse rate at the end of the run increased, then the 
oxygen consumption will also increase, hence his/her heart is functioning well. Based on the R commander
output below, check if the data on oxygen consumption and maximum pulse rate (from 152 bpm to 196
bpm) support Dr. Castillejo’s assertion.
