17 A drug company wishes to test a new drug A researcher assembles a group of volunteers and randomly assigns them to one of two groups one to take the drug and one to take a placebo In addition the company wants the experiment to be double blind What is the meaning of double blind in this situation A The volunteers in both groups are blindfolded when they take the drug or placebo B the volunteers in both groups do not know whether they are taking the drug or the placebo C Neither the volunteers nor the drug company executives know which volunteers are taking the drug and which are taking the placebo D Neither the volunteers nor the evaluator now which volunteers are taking the drug and which are taking the placebo E as long as the subjects are randomly assigned to the two groups there is no need to make the experiment double blind
