An article studied differences between expert and consumer ratings by considering medal ratings for wines, which could be gold (G), silver (S), or bronze (B). Three categories were then established. 1. Rating is the same [(G, G), (B, B), (S, S)] 2. Rating differs by one medal [(G, S), (S, G), (S, B), (B, S)] 3. Rating differs by two medals [(G, B), (B, G)] The observed frequencies for these three categories were 66, 104, and 42, respectively. On the hypothesis of equally likely expert ratings and consumer ratings being assigned completely by chance, each of the nine medal pairs has probability 1/9. Carry out an appropriate chi-squared test using a significance level of 0.10. State the appropriate hypotheses. O Ho: P1 = P2 = P3 = H3: at least one p; + 3 O Ho: P1 = P2 = P3 H: at least one p; + Pio O Ho: P1 = P2 = P3 = 9 H: at least one p, +- 9 O Ho: P1 = 1 4 P2 = H: at least one p, + Pio Calculate the test statistic.
