3) An inventor has developed a new spray coating that is designed to improve the wear of bicycle tires. To test
the new coating, the inventor randomly selects one of the two tires on each of 50 bicycles to be coated with
the new spray. The bicycle is then driven for 100 miles and the amount of the depth of the tread left on the
two bicycle tires is measured (in millimeters). It is desired to determine whether the new spray coating
improves the wear of the bicycle tires. The data and summary information is shown below:
Bicycle | Coated Tire (C) | Non-Coated Tire (N)
