Suppose μ₁ and ₂ are true mean stopping distances at 50 mph for cars of a certain type equipped with two different types of braking systems. Use the two-sample t test at significance level 0.01 to test Ho: M₁ - ₂ = -10 versus H₂: ₁-₂ < -10 for the following data: m = 8, x = 113.2, s₁=5.05, n = 8, y = 129.1, and s₂ = 5.35. USE SALT Calculate the test statistic and determine the P-value.
