A peach production farm wishes to improve the productivity of their orchard. The farm is looking to improve productivity by utilizing different pruning techniques anddetermine which one is best. These arrangements involve "square 1" (4X4S), "square 2" (3X3S), "triangle 1" (4X4T), and "triangle 2" (3X3T). However, the farm can only devote a specific area to this experiment, which is located nearby a river. The researchers are concerned that the river may influence their ability to identify the superior pruning technique. They have installed moisture sensors in a grid across the research area. The sensors report soil moisture, with a value of 1 being fully water-saturated soil.

After conducting the experiment, the farm has obtained the following data:

BLOCK TREATMENT Yield (ton/ha) 1 4X4S 12.434 2 4X4S 13.309 3 4X4S 13.570 4 4X4S 12.917 1 3X3S 12.186 2 3X3S 14.707 3 3X3S 14.337 4 3X3S 12.521 1 4X4T 14.303 2 4X4T 15.126 3 4X4T 15.367 4 4X4T 14.919 1 3X3T 13.133 2 3X3T 15.692 3 3X3T 15.499 4 3X3T 13.921
