Requirements:

1. Explain the null hypothesis and research hypothesis of the problem.

2. What should be the decision? Reject or Do not reject? Explain

1. Suppose that you wanted to compare your company's premium brand of tire (Brand A) against two major competitors' brands (B and C). You have set up a laboratory test of the three types of tires, and you have measured the number of simulated miles driven before the tread length reached a pre-determined amount. The hypothetical results are given in Fig. 8.6. Note that the data are in thousands of miles driven (000), so, for example, 63 is really 63,000 miles driven. TIRE MILEAGE TEST (Data are in thousands of miles) Brand A Brand B Brand C 62 61 65 61 62 67 62 63 71 64 60 66 61 64 65 59 64 62 63 62 63
