MIXED EXPERIMENTS- Diagram the following experiments and describe your randomization process. Indicate whether the experiment is completely randomized, randomized block or matched pairs. 1. We wish to determine whether or not a new type of fertilizer is more effective than the type currently in use. Researchers have subdivided a 20-acre farm into twenty 1-acre plots. Wheat will be planted on the farm. Describe the experiment. 2. Two toothpastes are being studied for effectiveness in reducing the number of cavities in children. Many studies indicate diet can affect the number of cavities. Assume there are 100 children available for the study. Describe the experiment. 3. An apple juice manufacturer has developed a new product - a liquid concentrate that, when mixed with water, produces one liter of apple juice. The manufacturer wants to see how potential customers will rate the liquid concentrate compared to their bottled apple juice. Describe the experiment. 4. It is common in nutritional studies to compare diets by feeding them to newly weaned males rats and measuring the weight gained by the rats over a 28-day period. If 30 such rats are available and two diets are to be compared, describe the experiment. 5. A family living in the hill country outside of Austin wants to determine which of two types of bird food will last the longest when used to fill the 6 bird feeders in their enormous backyard.
