In given Exercise, the maker of soft drink A claims its product to be "superior" to soft drink B. Given the results obtained in Exercise, do they appear to have a solid basis for their claim?
Exercise
A food expert claims that there is no difference between the taste of two leading soft drinks. In a taste test involving 200 persons, however, 55% of the subjects say they like soft drink A better than B.
If the food expert is correct, we would expect that 50% of the persons would have preferred soft drink A.
Under the assumption that the food expert is correct, what would be the probability of a "taste-off" in which 110 or more of the subjects preferred soft drink A?
