Suppose 𝜇1 and 𝜇2 are true mean stopping distances at 50 mph forcars of a certain type equipped with two different types of brakingsystems. Use the two-sample t test at significance level 0.01 totest H0: 𝜇1 − 𝜇2 = −10 versus Ha: 𝜇1 − 𝜇2 < −10 for thefollowing data: m = 5, x = 113.8, s1 = 5.07, n = 5, y = 129.5, ands2 = 5.35. A button hyperlink to the SALT program that reads: UseSALT. Calculate the test statistic and determine the P-value.(Round your test statistic to one decimal place and your P-value tothree decimal places.) t = P-value = Incorrect: Your answer isincorrect.
