## Statistics

Comparing means of three or more groups.

There are 4 auto body shops in a community and all claim to promptly serve customers. To check if there is any difference in service, customers are at random selected from each repair shop and their waiting times in days are recorded. The output from a statistical software package is:

 Summary Groups Count Sum Average Variance Body Shop A 3 15.4 5.133333 0.323333 Body Shop B 4 32 8 1.433333 Body Shop C 5 25.2 5.04 0.748 Body Shop D 4 25.9 6.475 0.595833

 ANOVA Source of Variation SS df MS F p-value Between Groups 23.37321 3 7.791069 9.612506 0.001632 Within Groups 9.726167 12 0.810514 Total 33.09938 15

Is there proof to suggest a difference in the mean waiting times at the four body shops? Use the .05 significance level.
