Many consumer groups feel that the U.S. Food and Drug Administration (FDA) drug approval process is too easy and, as a result, too many drugs are approved that are later found to be pushed for a more lenient approval process so that pharmaceutical companies can get new drugs approved more easily and quickly. Consider a null hypothesis that a new, unapproved drug is unsafe and an alternative hypothesis that a new, unapproved drug is safe.

  1. Differentiate Type 1 and Type 2 errors.
  2. Given the case scenario, explain the risks of committing a Type 1 or Type 2 error.
  3. Which type of error are consumer groups trying to avoid?
  4. Which type of error are industry lobbyists trying to avoid?

Solutions

Expert Solution

The hypotheses are

a) Type 1 error is made when we wrongly reject a null hypothesis which is true. In this case we would be making a type 1 error if a new drug is declared safe, when if fact the new, unapproved drug is not safe.

Type 2 error is made when we wrongly accept a null hypothesis which is false. In this case we would be making a type 2 error if a new drug is declared unsafe, when if fact the new, unapproved drug is safe.

b) When FDA commits a type 1, it risks approving a new drug that is not safe and there by having a potential adverse effect on the patient treated using this new drug.

When FDA commits a type 2, it risks not approving a new drug that is safe and there by denying a patient the treatment that could potentially be beneficial and also denying the industry a potential source of revenue.

c) The consumer groups are trying to avoid type 1 error as it has adverse impact on the patient who is treated using such a drug.

d) Industry lobbyists are trying to avoid type 2 error as it can deny the industry a potential source of revenue.
