Question
For the given alternative hypothesis Ha: M₁ M₂ < -10, the P-value will be the area under the t, curve to the left of t. Note that the table of t curve tail areas provides the area under the upper tail. Because t curves are symmetric about 0, the area to the left of -t is the same as the area to the right of t. Using the test statistic calculated previously, t = -1.9, and the calculated degrees of freedom, v = 15, refer to the table of t curve tail areas to find the area under the curve to the right of t = 1.9 rounded to three decimal places. P-value = area under the curve to the left of t = -1.9 = area under the curve to the right of t = 1.9 0.076 X Because the P-value is greater than less than 10. the significance level of 0.01, we fail to reject ✓ Ho. Therefore, the data does not suggest that the difference between mean stopping distances is
