Which of the following is a valid conclusion? TI
A pharmaceutical company develops a new generation
of blood pressure medication that may also help with
cholesterol. The research and development department
advertises in the local papers and online seeking
volunteers who already take blood pressure medication
to participate in a study for the new medication. Two
hundred people volunteer, and their current blood
pressure along with their cholesterol levels are
measured. They are randomly assigned to two groups,
one that takes the new generation of blood pressure
medication and one that takes the original medication. At
the end of the study, the subjects' blood pressure and
cholesterol levels are measured. The group with the new
medication is found to have a significantly lower overall
blood pressure than the original medication group. It was
also determined that the new medication did not
significantly lower cholesterol levels.
O Inferences can be made about all blood pressure
patients, and the conclusion can be made that the
new medication lowers blood pressure more
effectively than the original medication for patients
taking blood pressure medication.
