question 112

Essay

Use a Kruskal-Wallis test to test the claim that the samples come from populations with equal
medians. The table below shows the weights (in pounds)of 6 randomly selected women in
each of three different age groups. Use a 0.01 significance level to test the claim that the 3
age-groups have the same median weight. $$\begin{array} { c | r | r } \text { 18-34 } & \text { 35-55 } & \text { 56 and older } \\\hline 119 & 123 & 140 \\134 & 147 & 128 \\114 & 135 & 59 \\125 & 110 & 134 \\153 & 154 & 120 \\138 & 163 & 116\end{array}$$
