heart disease. A group of medicines- statins are prescribed by doctors to lower blood cholesterol.

medicine)

d) All in the group may choose to opt for either statin or placebo in the beginning of the study.​

Answer 2

Answer:

The correct option is b) Half randomly chosen people in the group be given statin and the other half a placebo (dummy medicine)

Explanation:

Placebos are used in clinical trials of medicinal drugs and are used in circumstances that either become better or worse, or they have an undetermined course. This way all the patients will receive equal treatment and care.

So, half randomly chosen people in the group are given statin while others are given a placebo.
