You have been selected to be part of a research team in your facility. Due to a possible batch of defective medicine X, your team has been asked to randomly select patients already receiving the batch to determine if treatment is causing recurrences of nausea. Your team has selected to separate patients into 3 groups: those who receive one batch within a week, those who receive two batches within a week, and those who receive three batches within the week. Your team decides to make the claim that at least one of your groups will have a noticeably different mean than the other groups.
