Using the same samples described in Problem 5, a researcher investigated how the income of fans of professional soccer in the United States and Brazil compared to the median national income in their respective countries. According to the sample data, 60% of professional soccer fans in the United States earn above the U.S. median income; 30% of professional soccer fans in Brazil earn above Brazil’s median income. Conduct a two-sample test with a

.05 alpha-level to determine whether fans of professional soccer in the United States are really more likely to earn more in their national median income than Brazilian fans.
