Over the years, the Food and Drug Administration of the United States (FDA) has worked very hard to avoid making type II errors. A type II error occurs when the FDA approves a drug that is not both safe and effective. Despite the agency's efforts, however, bad drugs do on occasion get through to the public. For example, Omniflox, an antibiotic, had to be recalled less than six months after its approval due to reports of severe adverse reactions, which included a number of deaths. Similarly, Fenoterol, an inhaled drug intended to relieve asthma attacks, was found to increase the risk of death rather than decrease it [17]. Is there any way for the FDA to completely eliminate the occurrence of type II errors? Explain.
