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) |
| SAMPLE PROPORTION OF X = | 0 | .422018 |
| SAMPLE PROPORTION OF Y = | 0 | .25 |
| PROPORTION X - PROPORTION Y = | 0 | .172018 |
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.
