Suppose p1 and #2 are the mean stepping distances at 50 mph for cars ofa certain type equipped With two different types of braking systems. The data follows: m = 9, 2 = 113.6, 51 = 5.02, n = 9, l? = 129.1, and 52 = 5.36. Calculate a 95% CI for the difference between true average stopping distances for cars equipped with system 1 and cars equipped with system 2. (Round your answers to two decimal places.) I USE SA Does the intervai suggest that precise information about the value of this difference is availabie? 0 Because the interval is so wide, it appears that precise information is not available. 0 Because the interval is so narrow, it appears that precise information is available. 0 Because the interval is so wide, it appears that precise information is available. 0 Because the interval is so narrow, it appears that precise information is not available
