The TIRE Company researcher wants to determine if her new type of tire wears better than the current tire types. She selected three existing types to be evaluated with her newly developed tire. She had four tire types, all of the same size. She had available four cars and four drivers which could be used during the driving test. The test was to measure the tread wear during a 25,000 mile driving test. Describe how you would design an appropriate experiment for her. Describe in detail the treatment structure and the design structure. Write down the appropriate model and key out the corresponding analysis of variance table; include sources and degrees of freedom.
