The international rice research institute in the Philippines conducted a study of the relationship between and the yield of rice and the amount of nitrogen fertilizer used when growing the rice. A number of small plots of land (all the same size) were used in the study with varying amounts of fertilizer from one plot to the next. When the rice is harvested, the yield (in ounces of rice) was measured and related to the amount (in ounces) of nitrogen...
