Gallup Asked a Nationally Representative Sample of Adults About Their

Multiple Choice

Gallup asked a nationally representative sample of adults about their alcohol consumption. Those in the sample who drank alcohol were asked which they drank most often-beer, wine, or liquor. Do the data provide evidence of an equal preference for beer, wine, and liquor as the favored alcoholic drink of American adults who drink alcohol? Here is an incomplete Minitab output for the corresponding chi-square test:

$\begin{array} { l r r r r } & \text { Test } & \text { Contribution } \\ \text { Category } & \text { Observed } & \text { Proportion } & \text { Expected } & \text { to Chi-Sq } \\ \text { beer } & 264 & 0.333333 & 216.667 & 10.3405 \\ \text { wine } & 237 & 0.333333 & 216.667 & 1.9082 \\ \text { liquor } & 149 & 0.333333 & 216.667 & 21.1328 \end{array}$
N DF Chi-Sq P-Value 650 Using a significance level of 5%, what should you conclude?

A) There are significantly more American adult drinkers who favor beer over wine or liquor.
B) There is significant evidence that American adults who drink alcohol do not favor beer, wine, and liquor equally as the alcoholic drink they consume most often.
C) The data are consistent with an equal distribution of beer, wine, and liquor as the alcoholic drink consumed most often by American adults who drink alcohol.
D) We are unable to conclude anything, because the test assumptions are not met.
