A cola manufacturer invited consumers to take a blind taste test. Consumers were asked to decide which of two sodas they preferred. The manufacturer was also interested in what factors played a role in taste preferences. Below is a printout comparing the taste preferences of men and women.

      HYPOTHESIS: PROP. X = PROP. Y

SAMPLES SELECTED FROM soda(brand1,brand2)

males(sex=0, males)(NUMBER = 115)
females(sex=1, females)(NUMBER = 56)

X = males
Y = females
SAMPLE PROPORTION OF X =0.422018
SAMPLE SIZE OF X =109
SAMPLE PROPORTION OF Y =0.25
SAMPLE SIZE OF Y =52
PROPORTION X - PROPORTION Y =0.172018
Z =2.11825

Suppose the manufacturer wanted to test to determine if the males preferred its brand more than the females. Using the test statistic given, compute the appropriate p-value for the test.
