WebThe value of the test statistic is: t = − 14.4 − 0 6.77 / 10 = − 6.73. The critical region approach tells us to reject the null hypothesis at the α = 0.01 level if t > t 0.005, 9 = 3.25 or if t < t 0.005, 9 = − 3.25. Therefore, we reject the null hypothesis because t = − 6.73 < − 3.25, and therefore falls in the rejection region.
