Four Different Types of Fertilizers Are Used on Raspberry Plants $$\text { Use } \alpha = .05$$

Four different types of fertilizers are used on raspberry plants. The number of raspberries
on each randomly selected plant is given below. Use the Kruskal-Wallis H-test to test the
claim that there is no difference in the distribution of the populations. $$\text { Use } \alpha = .05$$ $$\begin{array} { c c c c } \hline \text { Fertilizer 1 } & \text { Fertilizer 2 } & \text { Fertilizer 3 } & \text { Fertilizer 4 } \\\hline 13 & 12 & 13 & 10 \\12 & 15 & 10 & 12 \\13 & 12 & 11 & 10 \\14 & 12 & 10 & 11 \\14 & 12 & 9 & 12 \\13 & 13 & 10 & 11 \\\hline\end{array}$$
