A researcher investigates the average number of customer complaints per week received by three different service centers: Center A, Center B, and Center C. A random sample of weekly complaints was recorded over several weeks for each center, as shown below:At the 0.050.05 significance level, test the claim that the mean number of weekly complaints is the same across the three service centers. Based on your results, does it appear that any one of the service centers consistently receives more complaints than the others?

Problem 15Multiple Choice

A researcher investigates the average number of customer complaints per week received by three different service centers: Center A, Center B, and Center C. A random sample of weekly complaints was recorded over several weeks for each center, as shown below:

At the $0.05$ significance level, test the claim that the mean number of weekly complaints is the same across the three service centers. Based on your results, does it appear that any one of the service centers consistently receives more complaints than the others?

None of the centers appears different, all complaint rates are approximately equal

Center C appears to receive more complaints than the other two centers

Center B appears to receive more complaints than the other two centers

Center A appears to receive the most complaints, but the difference is not significant
