Suppose a clinical trial is testing an experimental drug against a drug that is currently being used.The old drug is effective, but many patients experience unpleasant side effects.Patients are divided randomly into 2 groups.The first half take the old drug, and 22% experience the side effects.The other group gets the new experimental drug, but only 11% experience side effects.

For the sake of argument, assume both drugs treat the disease equally well.

i) Describe what you would need to do next, from a statistical perspective, before you recommend prescribing the new drug rather than the old.That is, indicate you understand why we need an inference procedure, not just descriptive statistics.

ii)Discuss thepractical considerations(what is important about medications, both to patients and physicians)that should be addressed before subscribing the new drug.
