Explain the risks of committing a Type l or Type Il error. Choose the correct answer below. A. A Type I error would be incorrectly failing to approve an unsafe drug. A Type Il error would be incorrectly O B. A Type l error would be incorrectly failing to approve a safe drug. A Type II error would be incorrectly ° C. A Type l error would be incorrectly approving a safe drug. A Type II error would be incorrectly failing to D. A Type I error would be incorrectly approving an unsafe drug.

Explanation / Answer

a. The Type I error refer to the likelihood of incorrectly rejecting a true null hypothesis. Thus, if a researcher rejects that new, unapproved drug is unsafe, when actually it is unsafe, the researcher committs Type I error. Thus if researcher incorrectly approve an unsafe drug, he makes Type I error. Type II error refer to incorrectly retaining a false null hypothesis, that is concluding the new, unapproved drug to be unsafe when it is actually safe. Therefore, going by the analysis, one can discard options A, B and C easily. Option D is correct.

b. Consumer would like to avoid Type I error (incorrect rejection of true null hypothesis), as it would mean that too many unsafe drugs are approved. Thus, one can easily discard options A, B and C. Option D is right.

c. The goal of industrial lobbyists is to release more new drugs, that is to facilate drig approval process. Industrial lobbyists are trying to avoid Type II error (incorrectly retaining a false null hypothesis), as it would mean lesser number of new, unapproved drugs to be declared safe. Options B, C and D are discarded, leaving option A to be correct.
