Question 15

A tea manufacturer believes his company's tea (Tea A) has a very distinctive taste. He conducts a study to evaluate his believe. Five employees are asked to taste Tea A and two other tea's once, in random order and to try to identify which tea was Tea A. All five employees correctly identify Tea A. These results are encouraging. More quantitatively, according to the binomial distribution, if chance alone is at work, what is the probability of getting this outcome? If the tea manufacturer conducted another study similar to this one, give three things the manufacturer could do to alter the study so that if Tea A is really responsible for the result, rather than chance alone, he could have more confidence in the outcome. Assume good experimental design was followed in the original experiment.
