Suppose 𝜇1 and 𝜇2 are true mean stopping distances at 50 mph forcars of a certain type equipped with two different types of brakingsystems. The data follows: m = 7, x = 113.6, s1 = 5.04, n = 7, y =129.6, and s2 = 5.36. Calculate a 95% CI for the difference betweentrue average stopping distances for cars equipped with system 1 andcars equipped with system 2. (Round your answers to two decimalplaces.)
