question 140

Short Answer

TABLE 10-8
A few years ago, Pepsi invited consumers to take the "Pepsi Challenge." Consumers were asked to decide which of two sodas, Coke or Pepsi, they preferred in a blind taste test. Pepsi was interested in determining what factors played a role in people's taste preferences. One of the factors studied was the gender of the consumer. Below are the results of analyses comparing the taste preferences of men and women with the proportions depicting preference for Pepsi.
Males: n = 109, pM = 0.422018 Females: n = 52, pF = 0.25
pM - pF = 0.172018 Z = 2.11825
-Referring to Table 10-8, construct a 99% confidence interval estimate of the difference between the proportion of males and females who prefer Pepsi.
