Measuring the height of a California redwood tree is very difficult because these trees grow to heights of over 300 feet. People familiar with these trees understand that the height of a California redwood tree is related to other characteristics of the tree, including the diameter of the tree at the breast height of a person. The data in the table represent the height (in feet) and diameter (in inches) at the breast height of a person for a sample of 21 California redwood trees.
Interpret the meaning of the coefficient of determination in this problem.
Perform a residual analysis on the results and determine the adequacy of the model.
Determine whether there is a significant relationship between the height of redwood trees and the breast height diameter at the 0.05 level of significance.

Suppose that a customer is purchasing a car. He conducts an
experiment in which he puts 10 gallons of gas in the car and
drives it until it runs out of gas. He conducts this experiment 15
times on each car and records the number of miles driven.

To calculate the patient’s cardiac output, we divide the amount of dye by the area under the dye concentration curve and multiply the result by 60:Cardiac output = (amount of dye / area under the curve)×60. The table below gives dye concentration for a dye-dilution cardiac output. The amount of dye injected was 8 mg. Sketch the graph and rectangles. Shade the area of approximation. Estimate the area under the curve and calculate the cardiac output from this estimate.
