Pipeline operators estimate that it costs between $75 and $500 in U.S. currency to replace each seal, thus making the Clarkson longer-lasting valves more attractive. Tyco does business with pipeline companies around the world. Suppose in an attempt to develop marketing materials, Tyco marketers are interested in determining whether there is a significant difference in the cost of replacing pipeline seals in different countries. Four countries-Canada, Colombia, Taiwan, and the United States-are chosen for the study. Pipeline operators from equivalent operations are selected from companies in each country. The operators keep a cost log of seal replacements. A random sample of the data follows. Show the ANOVA output using EXCEL, discuss your table, report the findings, and write your recommendation. Use these data to help Tyco determine whether there is a difference in the cost of seal replacements in the various countries using Tukey's HSD test. (a = .05)
