Provide an appropriate response.

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?

▸ the corn yield recorded for each section of land

▸ the four types of soil

▸ the type of fertilizer (old, new, or none)

▸ the section of land (A, B, or C)

A farmer wishes to test the effects of a new fertilizer on her potato 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 potato yield is recorded for each section of land. How many levels does the treatment have in this experiment?

▸ 3 (old, new, or no fertilizer)

▸ 12 (sections of land)

▸ 4 (rocky, sandy, clay, or average soil)

▸ 1 (potato yield)

A farmer wishes to test the effects of a new fertilizer on her soybean 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 soybean yield is recorded for each section of land. What type of experimental design is this?

▸ double-blind design

▸ randomized block design

▸ completely randomized design

▸ matched-pairs design
