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. YSAMPLES SELECTED FROM soda(brand1,brand2)males (sex=0, males) (NUMBER = 115)females (sex=1, females) (NUMBER = 56)X = malesY = femalesSAMPLE PROPORTION OF X = 0.422018SAMPLE SIZE OF X = 109SAMPLE PROPORTION OF Y = 0.25SAMPLE SIZE OF Y = 52PROPORTION X - PROPORTION Y = 0.172018Z = 2.11825Suppose the manufacturer wanted to test to determine if the males preferred its brand more than the females. Using the test statistic given, for a one-sided test, compute the appropriate p-value for the test.
