Click here to view a table of critical values for the studentized range a. Perform a one-way ANOVA using a = 0.05 to determine if there is a difference in the average satisfaction scores for the three restaurants. Determine the null and alternative hypotheses. Ho: H1 Determine the appropriate test statistic. Fx =0 (Round to two decimal places as needed.) Determine the p-value p-value = (Round to three decimal places as needed.) State the proper conclusion. Ho. There sufficient evidence to conclude that there is |difference in the average satisfaction scores for the three restaurants. b. If warranted, perform a multiple comparison test to determine which pairs are different using a = 0.05. i Satisfaction Score Data X Compare restaurants A and B. Choose the correct answer below. O A. Since |XA - XB |> CRA,B, conclude that the means for restaurants A and B are different. Restaurant A Restaurant B . Restaurant C B. Since |XA - XB |> CRA,B. conclude that the means for restaurants A and B are not different. 16 17 13 19 14 O C. Since |XA - XB | CRA,C, conclude that the means for restaurants A and C are not different. C. Since |XA - XC| CRA,C. conclude that the means for restaurants A and C are different. O E. The multiple comparison test is not warranted. Compare restaurants B and C. Choose the correct answer below. O A. Since |XB - XC| > CRB.C. conclude that the means for restaurants B and C are different. O B. Since |XB - XC|
