Suppose μ1 and μ2 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: μ1 − μ2 = −10 versus ha: μ1 − μ2 < −10 for the following data: m = 8, x = 115.6, s1 = 5.04, n = 8, y = 129.3, and s2 = 5.32.
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.)
t =
p-value =
