Cardiac and respiratory function.

Is there a relationship between blood pressure (BP)and breathing rate(BR)?
Does heart rate(HR) always increase with increased activity?
What happens to cardiac output as you increase workload?

Two groups of Access students in the UK decided to make a pilot study of these and other trends by measuring BP, HR and BR of a wide sample of subjects. The following results are completely RAW DATA. You are invited to draw what conclusions you can!
