Conduct a multiple comparison of means by Tukeys method to determine exactly where the significant differences occur

Question:

Conduct a multiple comparison of means by Tukey’s method to determine exactly where the significant differences occur in Problem 31.


Data Form Problem 31

Political theorist Karl Marx is known for his theory that the working class, to put an end to capitalism  and establish a communist society, would eventually rise up and overthrow the upperclass  members of society who exploit them. One reason for the capitalist workers’ discontent,  according to Marx’s theory, is that these workers take no pride in their work because both the  work they do and the products that result belong not to them but to the capitalists they work  for. To test this insight, a researcher went to a large factory and interviewed people from three  groups—the workers, the managers, and the owners—to see if there is a difference among  them in terms of how much pride they take in their work. Given the following scores, with  higher scores representing more pride in work, test the null hypothesis that pride in work does not differ by class.
