Question
Suppose that you wanted to compare your company’s premium brand of tire (Brand A) against two major competitor’s brands (Brand B and Brand C). You have set up a laboratory test of the three types of tires, and you have measured the number of simulated miles or the distance driven before the tread length reached a pre-determined amount.
At the 5% significance level, perform an analysis to determine if the mean distance driven before the tread length of the tire reached a pre-determined amount differ significantly among the three tire brands.
