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:
?
$\begin{array} { l r r r r } & \text { Test } & \text { Contribution } \\ \text { Category } & \text { Observed } & \text { Proportion } & \text { Expected } & \text { to Chi-Sq } \\ \text { beer } & 264 & 0.333333 & 216.667 & 10.3405 \\ \text { wine } & 237 & 0.333333 & 216.667 & 1.9082 \\ \text { liquor } & 149 & 0.333333 & 216.667 & 21.1328 \end{array}$

A) H₀: p₁= p₂ = p₃ = 1/3
B) H₀: p₁= 264/650 p₂ = 237/650 p₃ = 149/650
C) H₀: p₁= p₂ = p₃ = 216.667
D) H₀: p₁= 10.34 p₂ = 1.908 p₃ = 21.132
