Four research teams measured the speed at which signals travel down a certain type of nerve fiber, and what each team wrote in its team notebook is shown in the table below. Suppose a later and more reliable measurement gives 85.0 m/s for the signal speed in the same type of nerve fiber. Decide which of the earlier measurements was the most accurate, and which was the most precise.
