Question

Suppose ?1 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 H0: ??-?2--10 versus Hai ??-?2 -10 for the following data: m = 5, x-114.5, si-5.05, n = 5, y = 129. 2, and s2-5.36. Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.) P-value State the conclusion in the problem context. Reject H0. The data suggests that the difference between mean stopping distances is less than-10 Reject Ho. The data does not suggest that the difference between mean stopping distances is less than -10 Fail to reject Ho. The data suggests that the difference between mean stopping distances is less than -10 O Fail to reject H0. The data does not suggest that the difference between mean stopping distances is less than-10
