The Time (In Minutes)it Takes to Assemble a Computer Component $$\text { Use } \alpha = .05 \text {. }$$

The time (in minutes)it takes to assemble a computer component for three different
machines is listed below. Workers are randomly selected. Use the Kruskal-Wallis test to
test the claim that there is no difference in the distribution of the populations. $$\text { Use } \alpha = .05 \text {. }$$ $$\begin{array} { c | c | c } \text { Machine 1 } & \text { Machine 2 } & \text { Machine 3 } \\\hline 26 & 34 & 22 \\25 & 23 & 19 \\26 & 32 & 23 \\24 & 27 & 25 \\27 & 29 & 24 \\25 & 26 & 21 \\26 & 30 & 31\end{array}$$
