Super Cola is considering a recipe change. There are two recipes under development: a sugary, sweet cola and a less sugary, mild cola. Researchers from Super Cola must determine whether consumers are more or less likely to buy the sweet cola or the mild cola. The researchers realize that the subjects might not like a less sweet cola after drinking a sweeter cola and vice versa. How should the researchers decide which cola should be tasted first? A. The researchers should flip a coin once and use the winning cola first on every subject, for experimental consistency. B. There should be only one cola tested per experiment to avoid confusing the consumers.C. The researchers should flip a coin to decide independently for each subject, to randomly assign the cola recipe for each subject.D. The sweet cola should always be tasted first because it will give the consumers a relief when they taste the mild cola.E. The mild cola should always be tasted first because no one would like it after the sweet one.
