The drugs usually used to treat high blood pressure do not affect blood vessels in the lungs.
Bosentan is a new drug being studied as a treatment for high blood pressure in the lungs. In an
experiment, patients treated with bosentan showed an improvement in the distance they could walk
without fatigue within 12 weeks. Design an experiment to test the effectiveness of bosentan as a drug
to treat high blood pressure in the lungs. In your answer be sure to:
• state the hypothesis your experiment will test [1]
state how the control group will be treated differently from the experimental group [1]
state two factors that must be kept the same in both the experimental and control groups [1]
state the type of data that should be collected to determine if the hypothesis is supported [1]
