This assignment is worth 10 points.

See syllabus for due date.

The Experimental Design
The following experiments were conducted on a healthy man with average blood
pressure.

In his experiments, he would first determine his blood pressure at rest

Then he would test a treatment to determine if it affected his blood pressure

He would take his blood pressure at various time points using a home blood pressure monitor

Questions
In the first experiment, he tested the affect of drinking a large, caffeinated coffee on
blood pressure
he measured his blood pressure at three minute intervals
Question 1: Write a hypothesis as to how his blood pressure will be affected by
drinking a large, caffeinated coffee.

Data for Answering Questions 1-5 This graph shows the patient’s actual systolic and
diastolic blood pressure at three minute intervals

Questions
Question 2: Why was the patient’s blood pressure recorded before he drank the coffee?

Question 3: From the data presented in the previous slide, draw conclusions about the affects of caffeine on blood pressure.

Questions 4 and 5: Would these conclusions be considered as a possible basis for a theory? Explain your answer.

Questions
In a second experiment, he tested the affects of smoking a cigar on blood
pressure
Again, he measured his blood pressure at various time intervals http://www.onetwentyovereighty.com/blood- pressure/blood-pressure-experiments/

Data for Answering Questions 6-8
This graph shows the patient’s systolic and diastolic blood pressure during the smoking of a cigar.
