Donated blood is tested for infectious diseases and other contaminants. Since most donated blood is safe, workers save time and money by testing batches of donated blood rather than testing individual samples. Workers perform a test to check if a certain toxin is present, and the entire batch is discarded if the toxin is detected. This is similar to using a null and an alternative hypothesis to determine whether to discard the batch. The hypotheses being tested could be stated as: H_0:H 0 :H, start subscript, 0, end subscript, colon The batch does not contain the toxin. H_\text{a}:H a :H, start subscript, start text, a, end text, end subscript, colon The batch contains the toxin. Under which of the following conditions would the testers commit a Type II error?
