Example 4: Are the treatments safe?
to avoid more
Researchers have developed a new medication intended to treat high blood pressure. Before the drug can be
approved for general use, it must undergo rigorous testing to ensure it is safe and effective. The testing
process involves a trial where the drug's safety is assessed. If there is convincing evidence the drug is safe, the
drug
will be released to the public. If there is not enough evidence of its safety, the drug will go back for
further research
and development.
a. In this context, what would a Type I error be?
b. In this context, what would a Type II error be?
c. Which is worse here, a Type I or type II error? Explain.
d. What could we do to avoid this type of error in future testing?
