5. The Bridgestone Bicycle Company purchases bicycle chains from a third party supplier. The chains are required to be within 0.25” of 54 inches in order to work properly. If the chains are too slack or too tight the derailleur will not work correctly. The chains are supplied by the Ajax Manufacturing Company and the individual links are not exactly uniform. They fluctuate around a mean length of 0.5”, with a standard deviation of 0.01”.

a) How many links should be strung together to form a chain?
