A biologist is interested in how the circumference of a tree is associated with its height. Statistics software was used to conduct a simple linear regression for the relationship between diameters and the height of trees in Raleigh, NC. Both perimeters and circumferences were measured in feet. The following equation for the regression line was given:

HEIGHT = 2.18 + 13.634 * CIRCUMFERENCE

If the circumference of a tree is 0.5278 feet, what is the predicted height of this tree? Give your answer to the three decimal places. For help on how to input a numeric answer, please see "Instructions for inputting a numeric response."

Answer #1

HEIGHT = 2.18 + 13.634 * CIRCUMFERENCE

circumference of a tree is 0.5278 feet

HEIGHT = 2.18 + 13.634 * 0.5278

predicted height = 9.376

    please answer abc show your work figure 6.1 7.31 Tree diameter confidence interval. A study of 584 longleaf pine trees in the Wade Tract in Thomas County, Georgia, is described in Example 6.1 (page 352). For each tree in the tract, the researchers measured the diameter at breast height (DBH). This is the diameter of the tree at a height of 4.5 feet, and the units are centimeters (cm). Only trees with DBH greater than 1.5 cm were sampled. Here...
