A farmer wants to determine which of two brands of cow feed is best for Cows on a farm. Before using one of the feeds on all the cows, the farmer decides
to conduct an experiment using 36 individual cows. Which of the two plans for randomly assigning the treatments should the farmer use? Explain.
Plan A: Choose the 18 cows that are lowest in weight. Feed Brand K to all 18 of those cows. Feed Brand L to the remaining 18 Cows.
Plan B: Choose 18 of the 36 cows at random. Feed Brand K to those 18 cows and Brand L to the remaining 18 Cows.
Plan B, because the sample of cows is randomly chosen
Plan A, because the cows that are lowest in weight need the feed the most and should be treated first
Plans A and B are equivalent because they both follow experimental design.
Plans A and B are both poorly designed because there are not enough cows to test.
The plans cannot be evaluated from the information given.
