Harvest. Does the use of inorganic fertilizer produce more harvest or organic fertilizer? A study had been conducted to identify whether the use of inorganic fertilizer or the organic fertilizer will produce more harvest for two different types of produce (tomato and potato) per hectare of land. Both plants are grown under the same conditions with the only difference being in the type of fertilizer used.

Three hectares of each plant are under consideration and the summary statistics from the study are as shown in the following table. Is there any evidence if whether the use of inorganic and organic fertilizers will produce different amounts of harvest in total (in tons per hectare)?
