780 men suffering from high blood pressure were randomly assigned to one of two groups.Over a four-month period,the first group received an experimental drug and the second group received a placebo.A larger decrease in diastolic blood pressure was observed for those who received the drug.The experiment was double-blind.Determine the nature and scope of the conclusion the study can reach.
A) Since the technicians administering the treatment could have been biased,no conclusion can be reached.
B) Since the physicians evaluating the results could have been biased,no conclusion can be reached.
C) For men suffering from high blood pressure,the drug appears to lower diastolic blood pressure.
D) Since there is no random assignment,there is no way to know that the drug caused the decrease in diastolic blood pressure; there could have been confounding variables.
E) For adults suffering from high blood pressure,the drug appears to lower diastolic blood pressure.
Diastolic Blood Pressure
The pressure in the arteries when the heart rests between beats, the lower number in blood pressure readings.
Double-Blind
A study or experimental design in which neither the participants nor the researchers know which participants belong to the control group, nor the test group, until the results are analyzed.
High Blood Pressure
A condition in which the force of the blood against the artery walls is too high, potentially leading to heart disease, stroke, and other health issues.
