A company wishes to test four different types of tires: A, B, C, and D. The tires’ lifetimes, as determined from their treads, are given (in thousands of miles) in Table 16.33, where each type has been tried on six similar automobiles assigned at random to the tires. Determine whether there is a significant difference between the tires at the (a) 0.05 and (b) 0.01 levels. (c) Give the STATISTIX analysis for this one-way classification or one-factor experiment.
