Suppose u, and Hz 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-samplet test at significance level 0.01 to test H, Hq - H2 = -10 versus H,: H, - H2 < -10 for the following data: m = 5, x = 113.2, s, - 5.05, n = 5, y = 129.1, and s, - 5.39. A USE SALT Calculate the test statistic and determine the P-value. (Round your test statistic to one decimal place and your P-value to three decimal places.) P-value - 0.000 State the conclusion in the problem context. Reject Ho. The data suggests that the difference between mean stopping distances is less than -10. Reject H,. The data does not suggest that the difference between mean stopping distances is less than -10. O Fail to reject H,. The data suggests that the difference between mean stopping distances is less than -10. O Fail to reject Ho. The data does not suggest that the difference between mean stopping distances is less than -10.
