A group of researchers investigated the effects of a drug called Pressure Drop Y on lowering
blood pressure in a group of men between the ages of 50 and 70 years old. The researchers did
the following experiment and obtained the indicated results: One group of 150 men took a tablet
containing Pressure Drop Y for 3 weeks – 95 of these men experienced decreased blood pressure
by at least 10%. Another group of 150 men were given a tablet with no added Pressure Drop Y

dependent variable in this experiment?
Amount of Pressure Drop Y
Blood pressure
The age and gender of the participants
The 3 week time period and sample size of 150
The group of men that received the pills with no added Pressure Drop Y
