1 - Fitness data. Various measures of heart and pulse rate were taken on men in a physical fitness course at N.C. State Univ. The information provided has the following information:
· 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.
