6. To compare the wearing qualities of two types of automobile tires, A and B, a tire of type A and one of type Bare randomly assigned and mounted on the rear wheels of each of five automobiles. The automobiles are then operated for a specified number of kilometers, and the amount of wear is recorded for each tire. These measurements appear in the following table. We wish to find sufficient evidence to indicate a difference in the average wear for the two tire types. Use a 10% level of significance for the following three methods: Tire A Automobile Tire B 10.6 10.2 2 9.8 9.4 3 12.3 11.8 4 9.7 9.1 8.8 8.3 a) Use the sign test. b) Use the t-test for independent small samples. c) Use the t-test for dependent small samples.
