A Cola Manufacturer Invited Consumers to Take a Blind Taste $X =$

Multiple Choice

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)

$\begin{array}{lll}\text { males } & (\text { sex }=0, \text { males }) & (\text { NUMBER }=115) \\\text { females } & (\text { sex }=1, \text { females }) & (\text { NUMBER }=56) \end{array}$

$X=$ males
$\mathrm{Y}=$ females

SAMPLE PROPORTION OF X $= 0.422018$
SAMPLE SIZE OF $X = 109$
SAMPLE PROPORTION OF $Y = 0.25$
SAMPLE SIZE OF $\mathrm { Y } = 52$
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.

A) .2119
B) .0340
C) .0170
D) .4681
