Let H1 denote true average tread life for a premium brand of P205/65R15 radial tire, and let u2 denote the true average tread life for an economy brand of the same size. Test Ho: H1 H2 5000 versus Ha: 1 H2 5000 at level 0.01, using the following data: m 40, x 42,100, S1 2200 n 340, y 36,500, and S2 1800 Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) P-value
