WebThe table below sums up the test statistic to compute when performing a hypothesis test where the null hypothesis is: \ [H_0\quad:\quad\mu_X-\mu_Y=\delta\] Testing for the mean of a paired sample We suppose here that $X_i$ and $Y_i$ are pairwise dependent. WebThe test statistic is compared with a lower critical value, and if it is less than this limit, the null hypothesis is rejected. Thus, a statistical test requires a pair of hypotheses; namely, \(H_0\): a null hypothesis \(H_a\): an alternative hypothesis. Significance levels: The null hypothesis is a statement about a belief.
