Final answer:
The effectiveness of Convenia in treating skin and soft tissue infections in pets is implied to be more than 75%, avoiding a Type II error where one believes the effectiveness is at least 75% when it is actually less.
Step-by-step explanation:
The question revolves around the effectiveness of Convenia in treating skin and soft tissue infections in dogs and cats. It is important to differentiate between statistical hypothesis testing, such as the conclusion that there is not enough evidence to support that a new flea shampoo kills more than 25% of fleas, and the effectiveness rates of drugs like Convenia. For Type I and Type II errors, a Type I error occurs when a patient incorrectly believes the cure rate for Convenia is less than 75%, when it is actually at least 75%. A Type II error is when a patient believes Convenia has at least a 75% cure rate, but the actual cure rate is less than 75%. From the choices given and the context of Type II error, the correct answer would be C) More than 75%, as this implies that Convenia has a high cure rate for skin and soft tissue infections, which would be consistent with not making a Type II error.
