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 identity 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.)

a. What is the probability that the sample will have between

50% and 60% of the identifications correct?

b. The probability is 90% that the sample percentage is contained

within what symmetrical limits of the population

percentage?

c. What is the probability that the sample percentage of correct

identifications is greater than 65%?

d. Which is more likely to occur-more than 60% correct

identifications in the sample of 200 or more than 55%

correct identifications in a sample of I,OOO? Explain
