· runpulse: Pulse rate while running 

· maxpulse: Maximum pulse rate

· rstpulse: Resting pulse rate

· oxy: oxygen consumption

Write a report describing the relationships between the different variable. Produce scatter, boxplots, histograms charts. Find the correlations among the variables and the limitations. 

2. – - In the following graphs, all of them have a correlation coefficient of about 0.72. Which one(s) meet the assumptions of some sort of association? Explain.
