An ecologist hypothesizes that birds with longer wing spans use wider tree branches. The ecologist captured male birds, measured their wing span and other characteristics in millimeters, and then marked and released them. During the ensuing winter, the ecologist repeatedly observed the marked birds as they foraged for food on tree branches. He noted the branch diameter on each occasion, and calculated the average branch diameter for each bird in centimeters. The measurement data are below.

The volume V, in liters, of air in the lungs during a five-second respiratory cycle is approximated by the model V = 0.1729t + 0.1522t2 − 0.0374t3 , where t is the time in seconds. Approximate the average volume of air in the lungs during one cycle.
The increase in carbon dioxide (CO2) in the atmosphere is a major cause of global warming.
