Question
In 1921 a classic set of experiments with chemical fertilizers were performed at the Rothampsted Experimental Station, an
agricultural research institute in Hertfordshire, England. Researchers applied different amounts of a particular fertilizer to 10
apparently identical plots of land. The results for one test, using identical seed grain, are listed in the table. Compute the
average and marginal product of fertilizer.
