Hоw wоuld yоu use а completely rаndomized experiment in the following study? Jаne works in the agricultural sector. She needs to find a new fertilizer to work with. She has a total of 50 plants to test. To determine if the fertilizer is effective, Jane uses an electrical conductivity meter to measure the electrical conductivity of the fertilizer and soil solution (EC). The EC value shows the total amount of fertilizer ions, such as nitrogen and phosphorus, in milliSiemens per centimeter. The optimal EC value for plant growth is from 0.8 mS/cm to 1.8 mS/cm and should not exceed 2.5 mS/cm. Jane uses the new fertilizer for 25 plants. After five days of applying the new fertilizer, she uses an electrical conductivity meter on the roots of all 50 plants to measure EC and monitor the level of nutrients in the roots of plants, which gives her an understanding of the effectiveness of the new fertilizer.
