3. You plan to conduct a marketing experiment in which students are to taste one of
two different brands of soft drink. Their task is to correctly identify the brand
tasted. You select a random sample of 200 students and assume that the students
have no ability to distinguish between the two brands. (Hint: If an individual has
no ability to distinguish between the two soft drinks, then the two brands are
equally likely to be selected.)
