The drag coefficient measured in model testing is often used to estimate the drag of actual systems (e.g., airplanes, cars, and ships). The drag force F is related to the drag coefficient CD , density p, velocity V, and frontal area A via the formula

In a test of a bus model, the following information was obtained:
Another factor that has been determined to affect the measurement is the data-transmission error for force, which has been measured to have a standard deviation of 0.01 kN (10 samples). Determine the drag coefficient and the total uncertainty in its measurement at a 95% confidence level. Explain your assumptions.
