The analysis in Exercise 25 uses South America as the omitted category. What would change and what would be the same had the analysis used the United States as the omitted reference category?
Exercise 25
A company operates in the United States, Europe, South America, and the Pacific Rim. Management is comparing the costs incurred in its health benefits program by employees across these four regions. It fit an ANOVA regression of the amount spent for samples of 25 workers in each of the four regions. The following table summarizes the estimates.
This analysis was done in dollars. What would change and what would be the same had the analysis been done in euros? (Assume for this exercise that 1 euro = 1.5 U.S. dollars.)
