the life of two brands of canned tires durability is a feature of interest to the manufacturer. Eight brand 1 tires and six brand 2 tires were tested. Customers prefer tires with high levels of life. The data below shows the life for both brands, in thousands of kilometers. (Image) a) Test the hypothesis of equality of variances for the life of the two tire brands. This is a two-sided (bilateral) test. Use an α = 0.05. b) Test the hypothesis of equality of means for the life of the two tire brands. Use α = 0.05. Which tire brands would you buy, if the price is the same?
