question 32

Essay

Four different types of fertilizers are used on raspberry plants. The number of raspberries on each of 24 randomly selected plants is given below. Use the Kruskal-Wallis H-test to test whether the distributions of the numbers of raspberries differ among the four groups.
Be sure to specify the null and alternative hypotheses. Use $\alpha = 0.05$ $$\begin{array} { c c c c } \hline \text { Fertilizer 1 } & \text { Fertilizer 2 } & \text { Fertilizer 3 } & \text { Fertilizer 4 } \\\hline 10 & 9 & 10 & 7 \\9 & 12 & 7 & 9 \\10 & 9 & 8 & 7 \\11 & 9 & 7 & 8 \\11 & 9 & 6 & 9 \\10 & 10 & 7 & 8 \\\hline\end{array}$$
