An agricultural officer wants to study the effect of four different fertilizers on the yield (in tons) of a specific crop. Since there might be variability from one plot to another plot, he decides to use the randomized complete block design. The data are presented in the table. \begin{tabular}{|l|l|l|l|l|} \hline \multirow{2}{*}{ Fertilizer } & \multicolumn{5}{|c|}{ Plot } \\ \cline { 2 - 5 } & \( \mathbf{1} \) & \( \mathbf{2} \) & \( \mathbf{3} \) & \( \mathbf{4} \) \\ \hline A & 100 & 80 & 68 & 125 \\ \hline B & 150 & 70 & 90 & 138 \\ \hline C & 120 & 110 & 85 & 60 \\ \hline D & 70 & 100 & 78 & 124 \\ \hline \end{tabular} Page 2 of 3 1422TME100092301 Test whether the type of fertilizer used has significant effect on the yield of the crop. Use \( \boldsymbol{a}=\mathbf{0 . 0 5} \).

A farmer wishes to test the effects of a new fertilizer on her potato yield. She has four equal-sized plots of land. One plot has sandy soil, one has rocky soil, one has clay-rich soil, and one has average soil. She divides each of the four plots into three equal-sized portions and randomly labels them A, B, and C. The four A portions of land are treated with her old fertilizer, the four B portions of land are treated with the new fertilizer, and the four C portions of land are treated with no fertilizer. At harvest time, the potato yield is recorded for each section of land. What is the response variable in this experiment?

Now, suppose that the agronomist is also interested in how a particular type of fertilizer, in addition to the variety, affects the mean rice yield. So, he randomly applies the combination of each variety and fertilizer (either the fertilizer is present or not present) to five plots in a field. Again, the yield[s] in pounds per acre were recorded for each plot. (a) What is the response in the study? (b) What are the factors in the study? What are the factor levels? (c) What are the treatments? What are the blocks, if any?

A farmer wishes to test the effects of a new fertilizer on her corn yield. She has four equal-sized plots of land-- one with sandy soil, one with rocky soil, one with clay-rich soil, and one with average soil. She divides each of the four plots into three equal-sized portions and randomly labels them A, B, and C. The four A portions of land are treated with her old fertilizer. The four B portions are treated with the new fertilizer, and the four C's are treated with no fertilizer. At harvest time, the corn yield is recorded for each section of land. What is the response variable in this experiment? A) the type of fertilizer (old, new, or none) B) the section of land (A, B, or C) C) the four types of soil D) the corn yield recorded for each section of land
