An international agricultural research group wants to compare a new variety of corn (Variety B) with a widely used standard (Variety A). Forty counties in lowa participate in the study and each county assigns two adjacent one-acre plots to the study. The plots within each county are randomly assigned so that one plot receives Variety A and one plot receives Variety B. After the harvest, corn yield is measured for each plot. Is this an example of two independent samples or matched samples? O A. Independent Samples O B. Matched Samples
