A sports agent wants to understand the differences in the annual earnings of players in different sports. The following table shows the annual earnings (in million $) of 52 athletes. For the Kruskal-Wallis test, the rank sums for each group are at the bottom of the table. For the Kruskal-Wallis test, the competing hypotheses are ________. A) H₀: m_F = m_H = m_Bask = m_Base, H_A: m_H ≠ m_Bask B)H₀: m_F = m_H = m_Bask = m_Base, H_A: m_F = m_Bask C)H₀: m_F = m_H = m_Bask = m_Base, H_A: Not all population medians are equal D) H₀: m_F = m_H = m_Bask = m_Base, H_A: m_Bask = m_Bask

The Kruskal-Wallis test is used to compare more than two independent groups. The competing hypotheses are that all population medians are equal versus not all population medians are equal. Choice A and B have the same null hypothesis but different alternative hypotheses, which is incorrect. Choice D has the same null and alternative hypotheses, which is also incorrect. Thus, the best choice is C, which has the correct null and alternative hypotheses.
