The article The Gap Between Wine Expert Ratingsand Consumer Preferences (Intl. J. of Wine Business Res., 2008: 335351) studied differences betweenexpert and consumer ratings by considering medal ratingsfor wines, which could be gold (G), silver (S), orbronze (B). Three categories were then established:1. Rating is the same [(G,G), (B,B), (S,S)]; 2. Ratingdiffers by one medal [(G,S), (S,G), (S,B), (B,S)]; and 3.Rating differs by two medals [(G,B), (B,G)]. Theobserved frequencies for these three categories were 69,102, and 45, respectively. On the hypothesis of equallylikely expert ratings and consumer ratings beingassigned completely by chance, each of the nine medalpairs has probability 1/9. Carry out an appropriate chisquaredtest using a significance level of .10.
