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. Using the p-value approach and α = 0.01, the appropriate conclusion is ________.
A) do not reject the null hypothesis; we can conclude that not all median annual salaries are the same
B) do not reject the null hypothesis; we cannot conclude that not all median annual salaries are the same
C) reject the null hypothesis; we can conclude that not all median annual salaries are the same
D) reject the null hypothesis; we cannot conclude not all median annual salaries are the same

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.  Using the p-value approach and α = 0.01, the appropriate conclusion is ________.
A) do not reject the null hypothesis; we can conclude that not all median annual salaries are the same 
B) do not reject the null hypothesis; we cannot conclude that not all median annual salaries are the same 
C) reject the null hypothesis; we can conclude that not all median annual salaries are the same 
D) reject the null hypothesis; we cannot conclude not all median annual salaries are the same

The p-value is less than 0.01, indicating that there is strong evidence to reject the null hypothesis that all median annual salaries are the same. Therefore, we can conclude that not all median annual salaries are the same among different sports.
