Cities across the United States have restaurants that offer themes associated with foreign countries. German-style food and drink have become popular since many communities started hosting Oktoberfests, but authentic German food restaurants offer the fare all year long. The following ratings, based on three categorical judgments of food quality, décor, and service, were assembled from different German restaurants located in various cities. The ratings were made on the same scale from 0 to 30 (the higher the better).
Is there any significant difference in the ratings given to the German restaurants in each category? Construct a one-way ANOVA table and test for the difference at the 0.05 level of significance.
a. Solve using the p-value approach.
b. Solve using the classical approach.
