In phytochemical research, the percentage content of a plant chemical extract used for drug production was being studied. It was believed that the contents could vary according to the country of origin of the plant and the plant type from which it is extracted, as well as the method of extraction. A 5×5 Latinsquare design was employed for the study and the responses in percentages are presented as follows:  Rows=country of origin, Columns=type of plant, and Latin letters=

extraction method. Analyze the data fully and report your findings.
