question 4

Multiple Choice

An agricultural scientist performs a 2-way ANOVA to determine the effects of three different soil mixtures on the sprouting time (in days) of three varieties of hybrid cucumber seeds. The following MINITAB output presents the results. $$\begin{array}{l}\text { Analysis of Variance for Sprouting }\\\begin{array} { l r r r r r } \text { Source } & \text { DF } & \text { SS } & \text { MS } & \text { F } & \text { P } \\\text { Soil Mixture } & 2 & 16.518519 & 8.259259 & 5.439024 & 0.014202 \\\text { Hybrid Variety } & 2 & 2.074074 & 1.037037 & 0.682927 & 0.517753 \\\text { Interaction } & 4 & 6.814815 & 1.703704 & 1.121951 & 0.377121 \\\text { Error } & 18 & 27.333333 & 1.518519 & & \\\text { Total } & 26 & 52.740741 & & &\end{array}\end{array}$$ Can the mean effect of the hybrid variety be interpreted? If so, interpret the main effect. Use the α = 0.05 Level of significance.
