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
Suppose Pepsi wanted to test to determine if the males preferred Pepsi less than the females. Using the test statistic
Z= 2.11825
given, compute the appropriate p-value for the test.
a) O 0.0340
b)
0.9660
C) O 0.0170
d) O 0.9830
