A test is being designed to compare the wearing quality of two brands of tyres. Six cars were randomly selected, equipped with one tyre of brand A and one tyre of brand B (the other two tyres are not part of the test) and driven for one month. The Table below gives the amount of wear (in thousands of an inch) that took place in such a test. Car Tyre brand 1 2 3 4 A 125 64 94 38 90 133 65 103 37 102 Do the sample data and provide sufficient evidence for us to conclude that the two brands show unequal wear at 5% level of significance
