question 83

Multiple Choice

Use a Kruskal-Wallis test to test the claim that the samples come from populations with equal medians. SAT scores for students selected randomly from three different schools are shown
Below. Use a significance level of 0.05 to test the claim that the students from the three
Schools had the same median SAT score. $\begin{array} { c c c | c c c | c c c } { \text { School 1 } } &&& { \text { School 2 } } &&& { \text { School 3 } } \\\hline 550 & 480 & 670 & 460 & 580 & 620 & 500 & 620 & 700 \\400 & 600 & 520 & 380 & 600 & 470 & 450 & 550 & 760\end{array}$

What would be the value of $R _ { 1 }$ that would be used in finding $H$ ?
