A company is trying to convince farmers from all over the country who all use the same popular brand of fertilizer that their new brand CORNPLOSION will lead to an increased crop yield. To compare which fertilizer is better, the farmers agree to an experiment in the coming year on a 10 acre large plot on their land. They will divide the plot down the middle and apply their regular fertilizer to one half and the CORNPLOSION to the other. It is believed that within different regions of the country, soil is similar because the water and minerals are the same in an area. The yields of corn (measured in bushels per acre) is recorded below along with other computed statistics.
