Hypothesis testing using ANOVA
Three different brands of all season radial tires were tested for wear characteristics. For each brand, 4 tires were selected and subjected to a standard wear test. The distance (thousands of kilometers) achieved by these tires is provided in the table below.
Brand 1 Brand 2 Brand 3
91 99 83
100 96 88
88 94 89
89 99 76
At the 5% level of significance, is there a difference in the mean distances achieved by each of the brands?
