Engineers at a large automobile manufacturing company are trying to decide whether to purchase brand A or brand B tires for the
company's new models. To help them arrive at a decision, an experiment is conducted using 12 of each brand. The tires are run until they
wear out, with the accompanying results. Test the hypothesis that there is no difference in the average wear of the two brands of tires.
Assume the populations to be approximately normally distributed with equal variances. Use a P-value.
