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. em spectrum summaryWebMinitab and R also can be used to test for normality.
