Each center randomly sampled 100 people who called during a two-week period. Callers rated their satisfaction on a scale of 0 to 10, with higher scores representing greater satisfaction. The sample means were 7.6 for San Jose, 7.8 for Toronto, and 7.1 for Bangalore. The table shows the results of conducting an ANOVA.
