Measuring the height of a Yellow Meranti is very difficult because these trees grow to heights over 300 feet. In 2016, a group of Yellow Meranti in Sabah’s Danum Valley was announced as the tallest tropical trees in the world. People familiar with these trees understand that the height of a Yellow Meranti is related to other characteristics of the tree, including the diameter of the tree at the breast height of a person (in inches) and the thickness of the bark of the tree (in inches). The file YellowMeranti contains the height, diameter at breast height of a person, and bark thickness for a sample of 40 Yellow Meranti trees.
State the single linear regression models where the height of Yellow Meranti is treated as the response or dependent variable while:
a) the diameter of the tree at the breast height of a person (in inches) is the sole explanatory or independent variable.
b) the thickness of the bark of the tree (in inches) is the sole explanatory or independent variable.
