Transcribed Image Text:Suppose \( \mu_1 \) and \( \mu_2 \) 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 \( H_0: \mu_1 - \mu_2 = -10 \) versus \( H_a: \mu_1 - \mu_2 < -10 \) for the following data: \( m = 5, \, \bar{x} = 113.2, \, s_1 = 5.05, \, n = 5, \, \bar{y} = 129.1, \) and \( s_2 = 5.39 \).
**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.)
- \( t = \)
- \( P\text{-value} = 0.000 \)
**State the conclusion in the problem context.**
- \(\circ\) Reject \( H_0 \). The data suggests that the difference between mean stopping distances is less than \(-10\).
- \(\circ\) Reject \( H_0 \). The data does not suggest that the difference between mean stopping distances is less than \(-10\).
- \(\circ\) Fail to reject \( H_0 \). The data suggests that the difference between mean stopping distances is less than \(-10\).
- \(\circ\) Fail to reject \( H_0 \). The data does not suggest that the difference between mean stopping distances is less than \(-10\).
