TABLE 11-4 An Agronomist Wants to Compare the Crop Yield of 3

question 135

Short Answer

TABLE 11-4
An agronomist wants to compare the crop yield of 3 varieties of chickpea seeds. She plants 15 fields, 5 with each variety. She then measures the crop yield in bushels per acre. Treating this as a completely randomized design, the results are presented in the table that follows.

Definitions:

Contact Metamorphism

The process by which rocks are transformed in composition and texture due to high heat but moderately low pressure, typically near a heat source like magma.

Tight Folds

Rock layers that have been bent very closely together, typically as a result of high pressure, forming narrow and sharp folds.

Cleavage

A property of minerals that allows them to break along smooth, flat surfaces, determined by the mineral's crystal structure.

Columnar Joints

Natural formations resulting from the cooling and cracking of volcanic rock into nearly hexagonal columns.
