Suppose, and level 0.01 to test H 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 test at significance H - - -10 versus - # < -10 for the following data: m., 113.2, 5.0, - 129.3, and s, - 5.35. Calculate the test statistic and determine the P-value. (Round your test statistic to two decintal places and your value to three decimal places)...
